[Q] microphone broken ? - Eee Pad Transformer Q&A, Help & Troubleshooting

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.

HELP!!!!! GF's Mini stuck in headset mode!!!

Well, I wouldn't be in as deep of a trouble if this were my phone... But I suggested the Mini to my GF.
Anyway, she was using headset earlier today and after she removed the headset, the phone is stuck in headset mode. Meaning no voice coming thru the phone's earpiece on both incoming and outgoing calls. She tried the headset again and voice is coming thru headset without problem, but once removed, it's still stuck. How do I get the phone out of headset mode please???? Anyone has similar problem before??? Please help!!!

hey hi ,
There are many ways of fixing this -
1)softreset
2)turn bluetooth off! if you are talking about bluetooth headset
3)where it says enable bluetooth headset on today screen - disable it
These might help you!
Regards
AMD
The socket has probably jammed internally, try insert pull out a few times making sure you pull sharply when removing, if this fails try inserting something slightly smaller and jiggling it about. I have also used a tiny squirt of WD40 which is like an easing oil for rusted or obstinate nuts/bolts/screws, also you can buy a spray called switchgear which is used for electronic components such as volume sliders/switches etc when they become sticky and operate intermittently. This is a well known problem on the xda 2.
Thanks guys, it's not BT and this is after many soft-reset I'll give WD-40 a shot. Thanks again!
I've got exactly the same problem here. My phone is bonded to a BT headset. Forgot to bring the headset and found that no sound, or extremely small volume, was coming out from the phone. Tried soft reset, deleting the bond etc. none of it works.
Would be interested in knowing what's the real underlying cause if anyone finds it out.
Hey Solitary, I'm in HK as well and I think it's a hardward rather than software issue. Coz. if I pull the headset, the normal clicking sounds can be heard from the phone, just not during voice calls, I think the earphone on the phone is somehow dead, looks to me like cold soldering
I'm calling O2 in the morning and demand an exchange, my GF only had this phone since 1/9 and besides this, on the unit we have, the voice quailty is also bad too
Hi, CL55,
You might want to read this:
http://www.coolsmartphone.com/index.php?option=articles&task=viewarticle&artid=58&Itemid=3
It seems it is an old and common problem for smartphones.
I've also read in a Taiwan forum that they have got exactly the same problem in Taiwan for the Dopod818.
But I wonder if it is hardware related. My problem is that I'm stuck in a BT headset mode, and I'd never touched the hardware headset socket. So either I have a different problem than yours or else it seems it's more likely a software problem.
Anyway, do tell us if you manage to solve it.
Can you confirm if you can hear the clicking sound from the buildin speaker now? Only no voice from the earphone, or no clicking sound from the buildin speaker as well? I really suspect I have a different problem
Yes I can hear all other sounds from the speaker loud and clear, except for talking over the phone.
So it seems I've got a BT software (or my BT phone hardware) problem but you've got a Mini hardware problem.
I was listening to some music through my headphones on my jam and I got a call, so i pulled the headphones out of the jack. Once i did that no sound would come out of the speakers, not even after many soft resets. I could still hear sound when i put my headphones back in, but nothing when i took them out. Then i tried making a call and pulling the headphones out of the jack while in the call and that fixed it. It must put the hardware in some bad state if you pull headphones out when there's a call?
i had this problem to but i've fixed it! hard resets doesn't seem to work so i pulled the battery out for a night and my speaker was working again try it!

[GPL] epicBT - Call Audio Router ( Epic4G ) - bluetooth/wired conflict hotfix - 11/26

This application is a hotfix for a really annoying (and potentially unsafe!) bug in the Epic4G:
http://code.google.com/p/android/issues/detail?id=11372
http://forum.sdx-developers.com/epi...audio-routing-on-epic-4g/msg115990/#msg115990
The long and sort of it is that when anything is plugged into the 3.5mm headphone jack, the phone will only play call audio over that jack.
In order to route the audio through the earpiece, bluetooth or speakerphone, you must pull the plug out of the jack. This is at the very least annoying, and at the very worst potentially dangerous if, for example, you're driving.
How-To
Download the APK attached below for your android version.
Install like any other APK using adb or your favorite file manager.
What it does
This simple application allows you to pick the audio device to use for call audio to override this behavior, and can be changed on the fly.
All in-call audio will be routed to the device you specify when something is plugged into the 3.5mm headphone jack. If nothing is in the jack, the default behavior for the phone applies.
This also allows you to use the Speaker Phone when the headphone jack is occupied, even though the button on the call screen is disabled!
Your configuration should persist between reboots.
What it doesn't do
This app does not route any other type of audio. Your music, notifications, etc will still play over the headphone jack or phone speaker.
Again, this *only* affects in-call voice audio, and only when something is plugged into the headphone jack.
Notes
This app completely overrides the options on the call page! If you want to switch outputs during a call, you will have to do it from this app - your call will not be dropped when changing the output device.
In order to route the call audio properly, the system's mediaserver service must be restarted, however.
This means that any other audio you have playing when you apply the change will be disrupted, and related services may force close. For example, Pandora will skip to the next song. Other applications may not behave that well.
Disclaimer
This app modifies files in the /system partition, so use this at your own risk! I am not responsible for any problems that arise from this hotfix on your device!
This is currently for the EPIC4G *ONLY* - Do not use this on any other device. Please contact me if you have a different phone which experiences this bug and I will see if I can get it working for you as well.
This is *BETA* software, a work in progress, please post here if you experience any issues, but I cannot guarantee it will work for you!
ROM DEVs, feel free to bake this into your roms in whole or part, I encourage it as this provides a workaround for a safety issue, but please give credit if you use or derive from this application.
Special thanks to UberPinguin - his initiative, debugging, code-diving and testing helped make this happen every step of the way!
Many, many thanks to everyone in #samsung-epic for helping me test and work this out.
Be sure to download the APK for the right android version on your phone!

If this works as described above I will be so f-ing happy. One of my biggest gripes, solved.
No sh#t! I was just about to start searching the Market for an app like this! Downloading now to test.
Thank you!

updated OP with source link
First of all,...Thank you, Thank you, Thank you for working on this... This was one of my biggest gripes with this phone and I couldn't understand why the "geniuses" at Samsung/Sprint couldn't get this right.
I've done some extensive testing in my car for the Eclair version and wanted to share my results:
For the most part, the app does what it's supposed to...but I did notice that:
1) the "on the fly" feature doesn't work so well. That is, when changing from one mode to the other, I had to reboot the phone to get the new setting to take effect. This feature would be great with an app like Tasker, which could automatically open up the app and ask you which setting you want to use when a headset/aux jack is plugged in,...thus giving you the flexibility to use the best option depending on your situation. Is there a way to tweak the app to recognize the switch without rebooting by resetting something like the mediashare service?
2) For some reason, the mic volume (volume heard on the opposite end of call) on the bluetooth setting is lower when the headset/aux jack is plugged in. I'm not sure whether the regular phone mic, speaker phone mic, or the bluetooth mic is utilized in this setting, but the volume is definitely harder to hear on the other end than when the headset jack is unplugged. I would guess about 20-25% lower. I tested this effect during the call as well by plugging and unplugging the jack while counting 1 to 10 and it's the same. Is there away to increase the sensitivity of the bluetooth mic when the headset jack is plugged in?
Donation coming if you can get this working! Thanks again.

Strange, it works well for me - it takes a second to switch outputs while mediaserver is restarting, but never had to reboot. I'll look into this, may have accidentally tweaked something in the last build.
UberPinguin and I are still looking at the sources to find a better fix that works the way it's supposed to - the trouble seems to be that Phone.apk is actually selecting the 'correct' source and setting options appropriately, but the underlying OS isn't switching outputs. Restarting mediaserver was the only workaround I could find for this.

I hadn't noticed any volume issues but truthfully I haven't been using the BT often because of this bug - I've just been letting my calls go to VM instead of crashing my car Volume selection should be working properly so I'll see if I can add something to select volume as well.
To be clear on the MIC, input should always be the proper input for whichever mode you choose - phone MIC for speakerphone and BT mic for BT HP/HS.
If you're on stock then the phone mic should be used when your wired device doesn't have it's own, however this is broken in all of our custom community kernels - Wired Headset mode should only be used when you actually have a wired headset with a MIC of it's own if you're using one of these, otherwise the phone doesn't enable any MIC at all.
I should note, that all my tests were conducted on outgoing phone calls. I don't know if incoming calls are any different. I am using the Syndicate rom.
If you can get the bluetooth volume issue resolved, I'll likely leave it there, but it would be nice to be able to switch on the fly to speakerphone mode when bluetooth isn't handy.
Question: Does the froyo version have the same implementation?
Please keep up the good work!

Yes, the froyo version is the same - Samsung used a different asound.conf in froyo ( added in some interesting VOIP pcm ), so this is the only difference between versions currently.

...So this should work on for Sip/VOIP apps like Sipdroid, 3CX, and Fring? I managed to pick up 3CX and Sipdroid through my bluetooth headset but no mic...meaning the other end could not hear me... There aren't that many good sip/voip soft wares out there for the Android today.. I rated Fring the BEST but with no bluetooth support.
EDIT: Nevermind... I read the post again.. I don't think this will do the job other than support for the actual phone.. but it would be nice to have that option for sip/voip as well.
The SIP/VoIP stuff may work better in Froyo considering there are dedicated PCM devices listed in the asound.conf - however I've never used any of these applications, so this is pure speculation.
You're correct, this does only effect in-call phone audio, those applications would be handling (or in this case, not) the bluetooth audio routing directly. I've found lots of other similar quirks with BT on the Epic4G, such as the << and >> buttons on my A2DP headphones not working.

Hell Yea! You rock! I Threw out a fairly long search sentence in google and actually found your post here. No sooner did I install and set it up that my phone rang while plugged into the car audio and FINALLY I can use my friggin BT headset without yelling hold on hold on I gotta unplug the stereo cable. This has really peeved me off since I got the phone. Now what I don't get is why this obvious flaw has been ignored by Samsung and Sprint. Nice job on making it work like it should. BTW running stock 2.1 with root. No bugs so far.
THANK GOD. someone fixed this. bugged me so much in the car when i'm receiving a call. will report any bugs.

As others, I'm very grateful for this fix. After trying it out, if it works for me, donation on the way.
Regarding the MIC: My experience, all the way back to pure stock (IIRC) is that there is no MIC at all when a two-channel, stereo plug is inserted (headphones, cassette adapter, etc.). Every time I've been driving, listening to something via the headset jack, when a call comes in I can hear the other party, but they can't hear me at all until I unplug from the jack. So, even though there was no mic plugged in and the device was correctly sending 2-channel audio out through the jack (usually to a cass adapter, so I can listen via my car stereo), but doesn't "do the right thing" with the mic, even though the hardware and drivers are capable of detecting the absence of the mic.
It should, of course, default to the BT mic if there is a BT connection, or the built-in mic otherwise. For some reason this simple flow-diagram logic eludes Samsung.
So I got my first experience with this today...worked great. I was streaming Pandora, phone call came in, music was paused and I answered the call. Once I finished the call, the music continued playing. Minor detail, but since I was on WiFi, is there anyway that the music could have kept on playing while I was still on the call for the sake of my guys who were still working while I was taking the call? It's great that the music paused and resumed by itself, but it would have been cooler to have it keep going while I was on the call.

Unfortunately Pandora's phone-state listeners control that, it'd have to be modified or their devs would have to add options for it. Would be cool though, I agree
I've got a hacked version of Pandora that allows unlimited skips, I'll have to ask the guy who did it to see if they can tweak that as well. Come to think of it, it'd be nice to have it keep going for the times I'm driving down the road as well so whoevers in the car doesn't have to sit there and listen to me blah blah blah.

Bluetooth mic doesn't work with voice search?

This just feels like I am doing something wrong or missing some setting somewhere, but this is what I am seeing.
I've tested using a Plantronics Voyager Pro+ as well as a BlueAnt S4 on an Evo with Synergy mod as well as an Evo with Fresh mod.
I can get the voice search app to open fine (using Blue Launch), the issue is that when I do the bluetooth microphone is no longer used and the microphone on the handset is used instead. This works fine in a quiet room, but fails horribly on the road. I've also tested this with other searching apps to verify it wasn't just the Voice Search app (default voice dialer fails as well).
You can test this yourself by sitting in a quiet room, starting voice search, then alternating blowing into the bluetooth mic then the handset mic. You should see the microphone icon on the screen fill up when you blow on the handset and empty to almost nothing on the bluetooth mic.
This seems like a major failing, something that shouldn't have been overlooked so I must be doing something wrong. How can I get my phones to use the bluetooth microphone when the bluetooth device is connected instead of the handset microphone?
Anyone have any idea or can point me in the right direction?

Question Joying Zlink (CarPlay) and an inability for anyone to hear me over voice calls

Hey all,
Anyone have a solution for callers not being able to hear you when the call is taken through CarPlay over Zlink on a Joying head unit? My head unit is: JY-VO133N4. When I unplug my phone I'm able to have phone calls work great over blue tooth, so this appears to just be a Zlink/CarPlay issue. I can hear the caller perfectly, they just can't hear me.
Edit, they actually can hear me, but I come through with very low volume and with static, I'm undiscernable on their end.
Possible that it's trying to use the mic on your phone and not on the HU. I've done tests and this is what mine does. Where is your phone when driving?

Have same problem. zlink use phone mic?
I have the same problem, try to rec an whatsapp audio and listen after, It sound same when you make the calls and I think and the sound is too looow and pooor. My bluetooth calls are great!!! what could be the problem?
Same problem here, which got worse after updating to IOS 14.8.
I can hear all people very clear, BUT they hear me very far and distant (so it is of no use).
It is NOT a hw mic issue, nor a headunit issue, because when I kill Zlink and use the audio unit's bluetooth, all works perfectly.
My bluetooth audio works fine, It is a pity that the calls do not work, it is the only thing need for work perfectly
I know this thread has some age to it, but I recently started having the same problem that while using CarPlay through zlink, any phones calls, no one could hear me, but mics worked when connected to android BT. Also worked connecting a Samsung phone through android auto. Only occurred using iPhone and CarPlay. Been going on for a few months and couldn’t for the life of me figure it out.
Even updated to iOS 15 and same problem.
Today I finally got it working!!
This is what I did. Hope it helps others.
Connect to the unit and let zlink connect and go into CarPlay.
From within CarPlay, open google maps.
Press the microphone button in the bottom corner of google maps. You should get a pop-up saying that you have to allow google access to the microphone.
Immediately look at your phone, you should have a request on the iPhone to allow google access to the microphone.
ALLOW IT!
Then press the microphone button again in google maps. It should now allow you to use voice for searching.
Now go place a phone call!
This solved the problem for me. Hope it helps others.
Thought I'd found a solution but there was no microphone button on CarPlays Google Maps

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.

I had issues with call quality and tried the suggested Sony XA-MC10 microphone.. Confirmed, people can now hear what I am saying. Thanks a lot.

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?
Or have you modified it?
