[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).

Howto AutoUse BT Pair for Media Audio?

I've touched on this question before but I may have been using some wrong terminology.
On my S3 I have successfully created a BT pairing with a BT Audio Device use which has a steroe out fed into my car's head unit's Aux In.
So, it is Auto-Paired. That is, when I step into my car and turn on the ignition thus powering up the BT Audio Device the paring is available to be used for Media Audio.
However, in order for my phone to route audio to the BT Audio Device I must enter the phone's BT menu and tell the phone to connect to the Device for Media Audio.
I can either do this through the notification pane to see pairings then tap the pairing to use for Media Audio or I can go through settings->BT and do the same thing.
Either way, it's a huge PITA to do this every single time I get into my car.
There has got to be a way to have the phone automatically route Media Audio through this BT Audio Device upon detection. My previous two phones had nowhere near the ability of my S3 but they had no issues whatsoever with automatically pairing and routing audio to this BT Audio Device.
Is the S3 really this stunted in the BT department? If so, is there an app that fixes this stupidity with grace and non-intrusiveness?

I feel ya, in the past, all I had to do was toggle BT on and go, now there's two or three extra steps which almost defeats the use of a toggle.
I just started searching for some answers and am honestly surprised no one else has made a big deal about this. If I find something, I'll post it up... For now, going to take a look at some system files and build.prop stuff, but it's not really my department.

Got some NFC tags and NFC Task Launcher hoping I could circumvent the BS with a hardware hack. But no, the best this does is auto toggle the BT radio and open the device selection screen where 2 more taps are required to actually use the device for media audio. Any new insight out there? Considering Tasker app but it is rather expensive and no free version to see if it does the trick.

My Bluetooth Auto Corrects Just fine to my cars Bluetooth... Toggle on and go. Running AOKP currently but it worked properly on stock, stock rooted, and Synergy as well.

I haven't gotten a chance to try this yet but I probably will tomorrow.

I haven't had any trouble with bluetooth devices reconnecting to my phone as soon as I power them on. I'm running cyanogenmod 10 rom.
Also you can get free trial of tasker from here tasker.dinglisch.net/download.html

It seems the issue may be primarily with BT Audio Gateways. I don't have this issue with my laptop at all and I'm imagining car head units rarely see this problem.
That said A2DP Volume App fixed this issue for me. Once configured I did have to manually set the device to use media audio one last time before A2DP Volume started doing it for me. I configured NFC Task Launcher to kill wifi, enable BT and launch A2DP volume when it contacts the tag in my car and it works perfectly. Since NFC Task Launcher front ends into Tasker and Tasker has the A2DP force connect plugin available I'm seriously considering getting Tasker for all the other cool features it can do besides scratching this particular itch.

You can fix this relatively easy by getting the app Tasker. I use it to do things like automatically start the music player I want when headphones are plugged in, to turning up the brightness automatically when I am getting an incoming call, etc. I am fairly certain you could set up the program to do whatever you want via bluetooth if you fiddle with it.
Gluck!

LOL, if you had only read the rest of the thread...
Yeah, Tasker cannot do this OTB but with the A2DP Connect Plugin it can. Or you can just run the A2DP Volume app and do the same for free.
That the A2DP Connect code is GPL it would be super sweet if our developers incorporated the magic into the ROMs so that a base install didn't need apps to do something so simple as automatically route media audio to BT gateways.

This happens to me when I use the wrong settings in my cars head unit. My Toyota gives me the option to pair as a multimedia device, a phone or both. If you set it up as just a multimedia device then you won't have some functionality. Check your head unit manual and try to re-pair. You might have to delete the existing pairing for it to work right.

Yeah, it's not a head unit, it's an audio gateway that basically is just a BT receiver with a stereo out and no interface so it is what it is with no configuration options. This issue with the S3 appears to be primarily related to these types of devices.

Oh okay. When I look under the bluetooth menu in CM10 I have a paired connection that I named Car Multi-Media and if I look at its settings I see profiles called Phone audio and Media audio. I'm guessing you just have a Media audio profile. Not sure how to help you there. Sorry.

[Q] Bluetooth Voice Command prompts not loud enough / Nexus 5 and Pioneer CD-BTB200

Hey,
I am having trouble with my Pioneer CD-BTB200 Bluetooth Adapter, which is a common problem, according to the very few available threads on the internet.
This also didn't work with any other Smartphone before i.e. Samsung S3 or Blackberry Bold 9700.
Cliffnotes:
-pairing, media streaming (different source) and receiving and making calls works great! No issues there
-transfering the contact list results in a big mess, I have to dig in there if I can figure it out or if I just transfer one contact after another....
-now for the problem.......I installed Cyberon Voice Commander because it gives me the best behaviour and voice recognition since I am a native German speaker. Google, Dragon and AIVC don't work really well. But it doesn't matter which voice assist app I use, because it is the Bluetooth adapters fault. The Nexus 5 is rooted and runs stock Kernel with KitKat 4.4.2.
When I press the voice dial button on my Pioneer AVH-P5000DVD deck it activates the Cyberon Voice Commander app (or whichever is set as default). so far so good, that is what I want.
But! the dialog between me and the phone is almost impossible because the output volume over the car speakers is way to low. I have to literally pick up the phone and look at it's display to see what the voice commanding app is doing because you have to wait until it is finished asking what I want to do. (just holding a phone is illegal in Germany)
Assuming the app understood me right and starts dialing everything turns to be fine from that point because the volume of the actual call is perfect!
When the phone talks back to me I have to crank the volume all the way up to understand it a little bit and then turn it back down fast before the phone call starts or it'll blow the speakers out....since my car is quite loud when on temperature I don't think I will understand anything when I am driving.
I heard that the app TASKER could be programmed to raise the Bluetooth volume at a certain point and then lower it again. I checked but it only goes up to 15, which I already have set before with the stock volume slider. Additionally I have no idea how to configure Tasker to (maybe) get rid of the problem.
Has anyone ever heard of a similar problem and / or has an idea how to handle it?
Again, it's only the voice command prompts that are way to quiet when I start the voice dialing function via Bluetooth, everything else is fine.

Fixed the issue with SoundAbout!

Now the voice prompts play loud and clear over the car speakers! Every other volume managing app failed miserably!
I used the latest Beta Version btw, going to buy the Pro Version soon.

I did very little changes to the settings, if anyone is interested I can hook you up with some screenshots

I have this issue as well. SO what did you have to do with this app?

Playing PUBG with headphones plugged in, voice chats goes through phone speakers.

I just got a Redmi Note 10 Pro. All is good except when playing PUBG with headphones plugged in.
All the regular gameplay sound goes through the headphones except for when my teammates talk through the voice chat. The voice chat audio gets routed through the phone's speakers instead of going through the headphones like all the other audio.
However, when using Bluetooth headphones, this problem doesn't occur.
I've tried restarting the device, restarting the game, changing game settings, but nothing.
I assume this is a software issue right? Otherwise I'll look to change the device.
Thanks.

This app (lesser Audio Switch) will solve it no root required but you have to manually change the settings everytime you want to use Speaker, headphone, int mic or headphone mice/ bluetooth

will update you just now , are you by any chance rooted?

Actually I have an idea, download the apk from somwhere on the internet
Download Apk editor
edit the apk
common edit : then change the Sdk? target version to 39
it should work from there
else some of these methods may be viable to your phone
Best answer: How do I change my default microphone on Android?
There is no way to change default microphone. Normally device use the inbuilt microphone as default unless you manually connect another microphone like handfree. How do I change...

LG CM2440 audio over USB AOA2.0 plays only one minute

I have a LG CM2440 micro hifi system that can play audio from an Android phone over USB using AOA2.0. I'm trying to use this feature and it plays fine but only 1 or 2 minutes and then goes silent. On the phone the app playing somehow freezes for a while and then continues without audio until USB is unplugged or playback paused and resumed. Anyone had a similar issue? I tested two phones and both behave the same so I belive it is the hifi system. I see nothing to tweak in regards to AOA2.0 in the hifi system or in the phones. Is there some secret menu that would allow to tweak AOA2.0?
Thank you!

Sounds like power management is shutting it down. Not sure what LG is using globally for that. Start there and make sure the app(s) battery setting is set to allow background usage.

I don't let it sleep and it plays fine when not plugged to USB. I think not likely to be power management.
Is there some way to test the AOA USB audio besides the hifi system? Some way to have a PC behave like an audio endpoint?

I doubt it's hardware unless the DAC you're using is incompatible or defective. You can transfer large folders to the PC? Either a settings or firmware issue, more likely settings.
Maybe a bad 3rd party app. May have altered hidden user settings even if it was uninstalled.
You want verification? Factory reset would rule out a settings issue including hidden settings.
However if you don't find the root cause (and avoid it) it likely will reoccur.
Play with it. Google search for others with the same issue, doesn't necessarily have to be the same model or OS version.

Thank you for suggesting!
Yes, I tried that, phone freshly reset behaves the same. Two different phones behave the same. I googled but find nothing relevant.
The USB connection remains operative because even when the audio fails the player still responds to the hifi buttons (play, stop... the player in the phone can be controlled by the buttons in the hifi system).
I opened the hifi system to see the route of the signal, the USB plug goes to a BX8805 IC that looks like an ARM processor and it outputs a PWM signal to the amplifier. Nothing to do there, likely a firmware issue. Maybe I could try some ADB debug but not sure how could I attach the phone USB to a PC and the hifi system at the same time.

USB playback apparently not fixable so I will stick with bluetooth playback (it seems to me that USB playback sounds better).
For future reference after some investigation I found the following "LG bluetooth remote" app that works properly. This app allows control of the hifi system from the phone.
