[Q] microphone broken ?

i opened my new transformer yesterday and loaded skype. tried voice chat and no-one could hear me. the sound recorder app shows slight movement if i tap the case where the microphone is, but bellowing into it shows no reaction. external headset mic works fine.
Is there some setting for input levels i hav'nt found yet? I would hate to be missing something obvious. Or should i just send it back

I think the built in microphone may be crap, I have fantastic results with voice recognition on my phone with a very small margin of error in recognition, on the transformer, the recognition is terrible.
I hope that it is a software issue where the settings can be changed to increase sensitivity.
If someone has a solution, please let us know.

update
the blue security tabs on the box were open, i thought my wife had opened it to check when delivered but she hadnt. I have sent it back to amazon and they are sending me a new one first class post, fair enough, it did seem a little second hand on close inspection. hopefully mic will work on the new one.
thanks

I had the same issue when I got mine, the mic was completely useless. After I rooted and installed Prime v1.4 everything works fine. Im assuming its an issue like the speaker imbalance where there is just an incorrect value somewhere in the code for mic gain or volume

Yeah, mine is crap too. I keep trying to do voice search to no avail.
I love this device, but man, it looks like they picked some really cheap parts for some items. Both my microphone and light sensor are not nearly sensitive enough to be usable, it's almost like they are just there to pad the spec sheet.
I find this so annoying, because previously I had a Nook color that I sold off because I wanted a true tablet, one with real Android support and such niceties as GPS, camera, microphone, light sensor, vibrating mechanism and notification LED that the Nook didn't have since it was designed as a e-book reader.
Now I find the Transformer has no LED (at least Nook had one on the cable), no vibration, light sensor and microphone that may as well not be there...

update
well i returned it saturday morning. new one arrived monday afternoon. great service amazon. anyway microphone works fine on this one so im happy everything else seems to be working ok so will see how i get on with it

when I record my voice in high quality I hear something like :
chchchichchch chchilly chchentenches and chcho bad chchound*
*(six silly sentences and a so bad sound)
I don't think it is a microphone problem, cause even with a half dollar microphone, sound can be better, no?

mic technology has not changed much in a while...its a commodity part that is bound to be afflicted by quality control and configuration...since there's an issue with the speakers it might also signal an issue with the Mic config

I think I agree.
If I put my mouth right next to the microphone, it will record my voice in an audible manner though not amazing quality. But it's not good enough for like voice searching or typing, not on my Transformer at least.

did you try to record your voice? the result is like under the water and the "s " sounds like "chchch ".
I tried a stereo bluetooth headphone with microphone integrated and the microphone isn't recognized. did somebody else notice the same.
the only satisfying way to chat or record with a correct sound is to use ordinary headphones with Microphone and it's not practical.

I did try to record my voice, that's how I arrived at that conclusion! Previously I had only tried to do voice inputs and failed, and just assumed my microphone was totally broken.
If I speak right into the microphone, then I can hear my voice okay... it's not distorted, just not amazingly clear. But this isn't really feasible, unlike a phone it's pretty hard to talk right into a tablet's microphone.
I haven't tried pairing Bluetooth headphones since mine broke before I bought the Transformer, but it should work for the microphone as well. You should check the Bluetooth settings page and make sure your Bluetooth headset is set to use both media and headset profiles, you need both to get audio playback and recording.

Ah, no clue then, sorry.
I was big on Bluetooth headphones but recently gave up on them as I found them too much hassle to use. Now I have a USB headset for the computer, it's great except that it won't work on Android.

on my laptop I use integrated microphone. works perfectly. on EEE pad I could use ordinary headset that works OK but imagine each time somebody wants to chat with you, finding your headphones , disentangle the wires and then answer. I confirm we live in the 18th century

We should all put some video on Youtube showing the microphone quality recording for example on 44'000 sample rate. This would make people think before buying that crap, and maybe ASUS will try to change that.
I'm really furious about Microphone quality. voice search is impossible and chat is really hard

I was using spashtop and tried teamspeak to test the mic. No one heard anything. When I used my bluetooth stereo headset and mic, it was fine. I have not tested further and am not sure if that was a spashtop thing or the mic completely failing, but since seeing this thread, I guess I should check it.

I swear the mic almost seems like it's been fixed in 8.4.4.11 update.
I just did a test using the built in voice recorder app, and speaking at a normal distance it recorded my voice pretty well!
Voice search still seems less than perfect compared to my Android phone, not sure why this is. But the mic itself is now recording sounds as well as one can expect of any mobile device.

Are you running on Stock ROM?
for me there is no difference of quality. try google search with a wired headset and you'll see how it is running fine.

[Q] Use bluetooth headset mic instead of phone mic

I've searched around on the forums for an answer to this but could never find anything that seems to match up to my issue.
I have a A2DP enabled headset and want to use it with apps such as Team Speak 3 beta, Vent, and other apps. But for some reason although phone media happily plays over onto my headset. My phone continues to only use the mic built into the phone instead of the bluetooth headset mic.
Any apps designed to use the headset specifically work (ie. normal phone calls, skype, vlingo) but otherwise apps ignore the headset mic.
I already tried using apps like BT Mono and Super BT Mono Froyo but they seem to only pipe audio to the headset, but don't do anything at all with the headset mic.
Does anybody know how to get the headset mic to be selected by apps instead of just the built-in mic?
My device is a Sumsung Galaxy S II ( I9100 ). Both Stock and CyanogenMod Gingerbread

good good good

Still hoping someone may know how to get the Galaxy S II phone to use a bluetooth headset mic instead of the built-in mic on the phone.
I'm really stumped on how to do this.

I still haven't seemed to have any luck finding a way to forcefully map apps to use the headset mic. I'm beginning to wounder if it's possible with the Android OS.

I have the galaxy s2 as well and I've retired several different things and have been unsuccessful with anything I've tried so far... Really difficult to drive and use vent without a headset.

Yeah I'm wanting to do the same thing.. I don't spose you've found a way in the last couple of months? Surely it can be done - may need to get a dev to write something for it though..

Sorry Lilfellabob, still no luck. I find it odd it's so difficulty to remap audio settings.
Even in Ice Cream Sandwich I can't find a way.

The app would need to be written to accept it. Its not a matter of your phone. Its the apps. Think about it for a min. If it works on apps made to use it but another app doesn't work then where does the problem lay?

The thing is, typically other apps should be able to re-route the app to use the headset mic. Alike how there are apps that can force other apps to use bluetooth audio instead of the phone speaker, even if the phone/headset can't use a2dp.

Only if the code is there for it to do it. If they don't code it in then it doesn't work.

I'm having a similar problem but slightly the opposite.
I pair my phone to a Bluetooth device that lets me hear phone output on my car's speakers. However, the phone tries to use Bluetooth for the microphone when none exists. I want to force it to use the on-phone microphone. I can talk and talk but no one can hear me, unless I set the phone output to speaker or handset, which implies setting the phone input to amplified built-in mic, or just built-in mic, respectively.
In the Bluetooth settings I can set to use the Bluetooth device for music or phone, but ideally I would want "Phone" to be separated into "Phone output" and "Phone input" so I could uncheck input (and thus use the built-in mic.) This should be implemented at the Android level so that the setting can apply to all apps.
The same problem occured when I wired (2-stripe phone-to-car audio only, no mic) my Palm Pre directly to my car. I just tried with my GNex and it was smart enough to use the built-in mic when a microphone-less plug was connected.

wrong. its in the kernel. the new firmware on the android is is capable to transmit Audio Steam to Headset device as Audio only. i wont go 100% against coding to force it to but if they wanted to theres have to be some kind of exploit to do so. lets say if skype were to find that exploit or code it, it would be probably violate android policy.

Actually, what's going on is Skype is using the 'bluetooth device' hook of some sort, just like other apps that support piping audio to the bluetooth headset. However most apps don't use the bluetooth device API/hook and just dumbly send their audio to 'default output device' and 'default input device' blindly and let the OS or Kernel decide where to send it.
The OS or Kernel when it senses a bluetooth device with the 'media' profile on it is present, it changes the default output device to the headset, but it doesn't seem to bother doing the same for the bluetooth mic for the default input device.
Because apps like Teamspeak 3 just blindly use default audio device because it doesn't use bluetooth APIs in the app itself, I have no way to make it use the headset mic.
I wish someone could make a mod or app that will allow mapping the default input to a bluetooth mic when present.

As far as I know, Skype has problems using the BT mike as well. In fact, they took a user survey regarding the issue for android and iOS users. However, I cannot find the results of that survey / study, and Skype recommendations thereof.
User choice to use BT mike seems so BASIC to me, I wonder how it was overlooked...!

Rooting will crack open the full power of your Android device!

Rooting the device would give apps or the user permissions to modify system audio controller's (idk if it is anything like ALSA or anything..) settings to make app use the audio channel for the bluetooth headset... an example for the Galaxy s2 i9100 i have is the radio app "Sprit FM" has a "volume control stream" setting which allows the user to select what volume "control" will control the volume of the app's audio output
anywho... i hope it helps a little

rwong48, I have now the same problem that you have described. Have you solved it with any app for Andorid?
Thanks!

Solution
I found an app that solves this problem on android devices, it's called btmono and you can find it in the Google store. I tried to post the link but I don't have enough posts under my belt...
Anyways, pair your device, open the program (such as ts3), connect to your server and then turn on btmono. Voila!
Well, I tried to delete this after I saw that you had already tried btmono, but I couldn't figure out how so just disregard this message.

I already tried btmono, sadly although it works for the output audio, it does *not* work with the headset mic. Programs like TS3 will still keep using the phone's built-in mic, not the headset mine despite using btmono. The only thing btmono does is pipe the output audio to the headset only.
Thanks for the suggestion though

I can't believe they haven't fixed that yet. It is so basic...

Hey guys I'm going through the same issues with my note 2. Svoice was the only one that works but its painfully slow and inaccurate.
Anyways I've tried utter! robin and aivc. Aivc works pretty good but at least it uses the mic.
Utter is really promising but no Bluetooth mic. The devs have acknowledged it though. So hopefully soon.
Update: AIVC has one downfall. The app can't open if the screen is locked like utter and svoice can when prompted from bluetooth. Also, it only listens automatically the first time. If you close it without killing the app, you'll have to press the mic icon manually every time (which takes away from the purpose of handsfree).

Low Audio Quality of Media While in Call/VoIP

Hi, thanks for reading.
Coming from an extremely weaker Sony Xperia c5 ultra e5506, the only time media audio quality was adjusted to be mono/lower bitrate was during cellular calls.
I regularly used​ discord as VoIP and played YouTube or music while connected to discord and the sound remained high quality stereo, same as when not using the VoIP application.
However on the Galaxy S8+ the audio for all media is changed to single channel mono muxed to stereo, extremely tinny sounding low bit rate the moment I connect to discord or similar VoIP application.
Does anyone know if there is a way to change the audio quality of background application media to not be reduced so significantly while using call/VoIP applications? Or is this just going to be how it is.. ?
Thank you.
Edit/Update: I just tested discord on my phone before last, the Galaxy S III, and YouTube audio quality is not distorted or downgraded while connected to a VoIP server... Overall make satisfied with my S8+ but I'll be fairly disappointed if audio quality multi tasking in an almost 10 year old phone, 5 predecessors behind, out performs it...

*bump* forgive me, I'm hoping more eyes see this and possibly have information... thank you

*polite bump* Anyone else experiencing audio bitrate quality problems? I have to imagine there are others that multitask on their phones and like to be in calls/voip and watch videos/listen to music/etc at the same time without insane drops in audio quality...

I have the same problem with my S8+.
---------- Post added at 09:54 AM ---------- Previous post was at 09:50 AM ----------
I did just find out that if you mute the MIC it will go back to original sound quality.

I have the same issue after upgrading from a iPhone 5s with perfect discord sound quality, to my S8+ which makes the call quality really compressed and bad unless my own Mic is muted. Playing any kind of media while in a call makes it sound like it's playing audio from a 144p YouTube video from 2004.
I use discord nightly and i really really wish there was a way around this. :crying:

Anyone have any additional info...? It's not as big a problem for me anymore however it's still annoying...
Thanks

I think I found the solution to your audio issue.
This is for Samsung 8+/8, I mean, it might work for other phones that are Samsung and run Android version 7.0 and Android experience version 8.1 along with latest OS updates.
1. bring down the top menu
2. hold and press on the Bluetooth signal (it should be already synced with your Bluetooth headset device)
3. You're taken to another screen: Click on the three dots to the top right
4. On that little menu that pops up, go to and click on media volume sync
5. If it is off, make sure this option is on, and adjust your Bluetooth volume to max (optional)
6. That's it, it should now be able to play all audio on highest quality.

Thanks for your reply TangoNcash. It seemed to have helped somewhat. The call quality has improved, but the sounds from other apps (such as youtube/spotify) are not. They remain with the same, bad (bluetooth(?)) call quality. The weird part is, it does not seem to affect games (I run them from the game launcher).
While it is expected to have the bad quality with a bluetooth headset, this problem (bad codec) is appearing on wired headphones for me. A problem that was not there with my Samsung S6. I'm planning to go by a samsung service point later this week. Does anyone have found a solution to this problem?

I'll have to revive this thread, I have the same problem with my Zenfone 2, if I enter a Discord channel or WhatsApp call the media audio just gets to be "supressed" like it's very low quality or some audio noise reduction is going on. That really messes things up as you want to use Discord and play with your friends at the same time, but can't hear steps in games, I also found out that if you active your mic in games (at least in PUBG) it does the same. All problems happens with wired and bluetooth phones.

The same thing happens for me, even in oreo, there's no solution for this? Really?

Unfortunately I can only verify for my Huawei Honor 8, Android 7.0.
Tried Voice Apps: Discord and Hangouts
Tried Media Apps: Spotify and bundled Music Player
The music drops in bitrate, it gets heavily filtered, and volume fluctuate.

SOLUTION
All you have to do is open a voicemail and put it on hold, boom clear discord.

I know this isnt a solution, But I was having this issue in Discord on android in a channel I was solely wanting to listen to music in, not talk. What I did was a went to my bluetooth headphones in the bluetooth settings and unchecked "Phone calls"
This left only the higher quality audio modes and now Discord plays good audio and uses my phone mic if I ever did want to talk.

I found a solution, but you'll have to do this every time you intiate a call. It doesn't take long though:
Step 1: Launch the Discord app and go to settings
Step 2: Select "Voice & Video"
Step 3: Scroll down and make sure "Audio Mode" is set to "Call Mode"
Step 4: Initiate a call
Step 5: While on the call, open a vociemail then hang up
You should now have clear audio.
I've only tested this with wired headphones btw.
I've been having suppressed and terrible voice quality on my galaxy S8 too. And this method seems to work for me.

I seem to be having these issues as well when it comes to my p20 pro. Exact same issue with the filtering and down graded codec. It only reverts to pure quality if I make a phone call to anyone or my voicemail whilst in a discord call or server. The issue here is my mic volume gets dropped dramatically that no one can hear me talk unless it's pure silence and quote "if I don't breath I can hear you". Now that I'm seeing it happen on not just my Huawei device but a Samsung as well, including the fact you have a headphone jack (I only have a usb adapter) this gives me some hope that it's not just some hardware limitation. Other than the similar temp solution of having a phone call at the same time, has anyone fooled around with the developer options?
Phone: p20 pro
Headphones: wired headphones or Bluetooth
OS: Android 8.1 + emui 8.1

Quick revive
Okay we need this revived because I hate this and need an answer!

Guys, I figured out a wokraround! All you need to do is go into game launcher and add the app as a game. In my case it was Spotify. And then magically it worked perfectly. Don't know why this is only restricted to games but at least it works.
Edit: This only worked with Discord, and I don't believe that it was directly caused by this but by changing some settings in Discord.

What do you mean add the app as a game? You mean on my actual pc version of discord? What about Netflix and YouTube which don't necessarily have a program. Or is there another method you meant.

someone have a solution? pls

This solution has plagued me for months. I'm on the latest version of Android 8.0 and am pretty sure it's a problem with Android. I couldn't find a way around it, until today!
This specifically works with Discord, and getting good audio quality while on a voice call with someone. I like to be on voice calls almost 24/7 so it drove me crazy not being able to listen to any other kind of audio.
Anyways, today there was a new setting in Discord that fixed everything for me:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Go inside your Discord audio settings and enable Force Calls to use OpenSL ES and Call Mode. Both seem to solve this issue to have audio become high quality again.
Sorry for reviving this thread, but this is the first result on Google when looking for low quality VOIP media audio, and I'd like to provide a solution for anyone else who was like me and plagued with this issue.

Question Poor Bluetooth call quality

Greetings. I am the owner of a FYT UIS 7862 device. I have now done all the workarounds regarding the poor microphone quality during a call via Bluetooth.
I have connected an external microphone and disabled the internal microphone (via adhesive tape on the two contacts).
Here is the external microphone: https://m.de.aliexpress.com/item/1005001585070997.html?gatewayAdapt=Pc2Msite
Then I reflashed the firmware with the config.txt and this content:
persist.sys.zlink.mic.vol=9.9
persist.audio.mic.senstivity=1
persist.btmic.gain=10
persist.btspk.gain=7
Nevertheless, the call quality is really extremely poor. Then I installed a recorder app and recorded my voice. The test showed a clear sound image, it really sounded very good. But as soon as you make a call via Bluetooth, the quality is very poor.
Does anyone else have an idea what I could do? Thank you guys.

I had the same issue with Mekede M300S FYT116. This extra content is not valid for this unit, flash back the original config.txt and try.

The same for me, anyone has solution on this?

IMHO : Change the microphone !!!
I think I tested about 15 microphones (recovered from various devices) until I found one that works perfectly.

I have now ordered a Sony XA-MC10. Will report on Monday whether it works. If Sony is no good, what then?

I also ordered an expensive Panasonic microphone. But, unfortunately, I was not satisfied with him; also by testing several microphones I solved the problem. The "winning" microphone is a no-name.I don't know exactly, but it could come from a mobile headset...

I connected the Sony microphone today and what can I say: it works perfectly. Now everyone can hear me clearly and understandably. By the way, I paid 25€ for the Sony XA-MC10 new (on eBay) and can highly recommend it.

I'm glad you've sorted it out. Can I make you a question about your bluetooth connection? I also have a FYT 7862 and calls occurs without problem, but regarding the bluetooth connection: does your radio connects to your phone as soon as your get inside your car or do you have to connect it manually?

For me, the smartphone connects immediately with Bluetooth of the headunit. It takes one second.
But the headunit always connects automatically to the last Bluetooth connection. If I was connected and then my wife drives the car, she has to connect manually. The same then when I drive again afterwards.

Thank you for replying. Ok, so my unit does exactly the same but it doesn´t keep "My Favorites" on the main screen, it wipes it all, through the change. Does yours keep the "favorites" of each of one connections?

Once again regarding the Bluetooth connection: I put a button on the home screen of my wife's smartphone and mine. You click this once briefly and it connects immediately with the head unit, should it not happen automatically. This saves a few annoying clicks on the smartphone. You can easily do this via Macrodroid.
Regarding the favorites: No favorites are deleted, everyone has his own. I do not have this bug.

Thanks for that tip. In fact it saves a bunch of time! I'll see with the developer why my favorites get wiped.
Macrodroid is a powerfull one.

hi, did you replace the microphone or did you also disable the internal microphone.

I have replaced the microphone. Also my head-unit had a setting in its Factory Settings an option to choose internal or external microphone. I Opted for an external one there. But even with this setting with the included microphone and one other, the other party in the call could barely understand what I was saying. Since I have installed the Sony XA-MC10, I can have a normal call. Yes, people say there is interference and noises while driving, but the call apparently is clear enough. Maybe it is worth mentioning previous two microphones were center windshield close to rear-view mirror. This one is installed on the left-side roof-support (or whatever it is called), a bit closer to me.

Same here, it's a good microphone. My unit doesn't have an internal microphone so no interference issues.
The only issue left is a bit annoying still: The other person hears an echo of its own voice, I guess my unit picks it up from the speakers and transmits it back to the other person - the echo stops once I mute the microphone.
My voice is clearly heard (unless I mute of course).
Must be software related, because the issue doesn't exist in calls using Microsoft Teams and the like (installed on the unit and using the same microphone and speakers).

Thanks for providing the solution with the sony microphone, but I wanted to ask you about the most recommended configuration of the "config.txt" file.
Did you respect the factory settings?

If you put a search string "problem mic headphones" in XDA forums, you'll get tens if not hundreds of threads which start at least in 2015 and consider Xiaomi as well as Samsung, OnePlus, sometimes Moto phones - both on vendor and custom OS. Most of the threads are created in model specific subforums and most of them are left unanswered, even though the issues repeat from time to time, from one manufacturer to another. If I catch it correctly, Xiaomi (Redmi, Mi) is the champion in this field. But problems persist in other phones too.
One of the biggest issues often reported is that one day (or from the very beginning) when you put headset jack in, your interlocutor hears you badly. Your voice is too weak or ambient noise is too loud in respect to your speech. In many cases a proposed solution is 1) to install Mic Fix module for Magisk (on rooted phones). But it does not always work. 2) To change the headset and 3) to clean the physical jack hole. In many reported cases this does not help neither. So, there is a software switch which does not work.
I entered the club and having this precise issue with my Redmi Note 10 Pro running first on vendor Miui then on CrDroid 8. I changed three different wired headsets, including the one by Xiaomi, with no result. Installed Mic Fix module for Magisk (both latest updates), with no effect.
Manipulating the phone during the call or during a test record (bringing it closer and further to the mouth, putting it into my pocket with headset attached, etc.), I acknowledged that the problem is that the phone takes inbound audio signal from the phone built-in microphone and not from the headset. Both in mobile calls and in various messengers. Meanwhile listening to my interlocutors, as well as music alone is just fine.
Trying to solve the issue I found several great apps and Magisk modules, such as Dolby Atmos and Viper4Android FX equalizers which enhance your listening experience. But I found no clearly designated app or module which lets take control of the microphone when headset is attached. Literally no dedicated app or feature in all-rounder apps lets tweak the mic use. Meanwhile the issue persists during at least 7 years.
Maybe the solution is so evident, and the app/module is so easily and widely used that it's a shame to discuss such a noob topic? Please break the silence and tell which tools you use for tuning or tweaking your mic in the headset.
And if you already faced the same or a similar problem and found the same (zero) software solution for Android, what is the rational reason why such an app or module was not yet made by an expert and creative dev?

By now a solution that I found is to use a bluetooth headset. In this case the mic works well during calls.
But I like using wired headsets (and sound quality of mine wired is better than those on bluetooth). So I am still in search for an app or module to tweak or fix the mic redirection issue.
If someone can help, please be kind to give a hint.

Same here my man, and although my issue is slightly different, it's looking for the same solution, an app to tweak the mic
I'm using a oneplus 3 and my favorite ROM is Resurrection Remix (A10), but, if you use CTIA headsets (mine are earbuds because i don't like in-ear), sometimes the headset gets detected as OMTP and the mic produces a really loud hight pitch noise
So far i haven't found any solution, besides reconnecting the headset several, several times until it gets it right
