Enable Phone Mic With Call Audio Through Bluetooth? - AT&T LG Optimus G

Here's my situation: In my car, I often have my OG connected to my stereo with an A2DP bluetooth audio receiver (without a mic). This works well for listening to music, or getting directions from the nav. However, if I answer a call while connected to it, I can hear the audio through my car speakers, but the other person can't hear me. I understand that the OG's internal mic is disabled at this point, as it is expecting a bluetooth mic to be connected. The work-around I have found is to disable bluetooth for phone calls. This plays the call audio through the phone speaker, and utilizes the internal mic like normal speakerphone.
What I would like is a mix of the two. I want the call audio to play through the car speakers, but enable the OG's internal mic so I can talk through that. Does anyone know of an app or setting I'm missing that might accomplish this?
Thanks.

No, but that sounds like it would be really easy to code if you wanted to learn some java.
(Disclosure: I don't know java)

I was hoping to use this in the next few days. I don't think I can learn java that quickly. But I agree, it seems like it should be pretty easy to accomplish. Software turns the mic off, it should be able to turn it back on.

Hi Digil,
Did you find a way of doing this? I have a Galaxy Note 2 with the same setup in my car and I was wondering if you found a solution...
Thanks

Hey Ishkatar, nope I didn't find a solution yet, but I haven't spent too much time looking. I've been busy with work and traveling to see family on this holiday weekend. I'll definitely post here if I find anything.

The SoundAbout app seems like it will work when the phone is connected to a headset (audio out through headset, input via phone mic). But I can't find anything that will accomplish that when outputting audio through BT.

Yes, I tried it and it did not work with BT... After much research and testing multiple BT Manager apps I decided to return the BT adaptor and I'll think about buying a full BT hands-free connector...

Yeah, I think I might be forced to go with that Belkin adapter shown in the link above, which Is too bad because I was hoping not to spend anymore money, haha.

phone mic instead of bluetooth device
I had the same problem. I got fed up and decided to move the bluetooth mic to a more convenient location in my car, since I could not disable it. Before I re-positioned the un-soldered mic to a new location, I decided to make sure my soldering did not inadvertently damage any of the device. To my delight, without the mic being physically present, it defaulted to my phone mic. So, for me at least my problem was solved by removing the mic in question. I have no idea if it will work on other bluetooth devices.

any progress?

Just for info, after much research I don't think this is possible as Android does not allow routing of call audio to A2DP at all, probably due to security reasons?

I just plug a lead to the headphone jack and patch into the auxiliary input of my stereo. I also had one of those USB dongal Bluetooth receivers that worked exactly that way but it stopped working and other ones don't work, the one that did work was able to connect to phone audio as well as media audio. So it seems that if the mic can be disabled form the other end the Android mic will kick in. Android OS sucks you cannot do anything with the hardware. PC's piss over Google.

They probably don't do it because of latency error affecting feedback canceling. And what has external hardware got to do with security. Google just uses it as an excuse to getaway with marketing an inferior OS.

I wonder if I can replicate this. I need to kill the awful mic in my car Bluetooth so I can use phone mic

Has anyone tested this with non-native Calls like Skype, Facebook Calling, Zoom.US, what's app etc.?
it's totally unacceptable that I can use A2DP stereo audio + Computer Built in Microphone, but I can't do this with android!
Companies are taking off the headphone jack but they haven't figured out HD Bluetooth microphones yet!

Are any updates on this thread? maybe some apps could rout mic?

call routing thru 3.5mm Jack issues

I'm using obsidian v2 froyo build. Music and navigation work fine thru the headphone Jack when attached to my car stereo. However when a call comes in or if I'm trying to make a call I get nothing. I've searched thru various forums and others are having the same issue but could not find a solution. Any help would be appreciated
its a "feature" of all the froyo roms. froyo seems to want to ignore headphones without mic as it has a self-esteem problem and does not trust the quality of its mic at a distance.
it seems to be a kernel issue and won't be able to be addressed until they devs have source. only alternative is to have a cable with an in-line mic. that works for most of the roms. (i would say all, except i just flashed latest macnut and its not working )
EDIT: also, don't post this in dev forum. i answered nicely, but this is not the appropriate venue.
So why does it work for some and not for others
wait, so audio out still works fine but NOT the in-line mic?
sorry for the noob question, but i was going to flash obsidian later this evening, and i really need the 3.5 audio out. don't really care about using in-line mic headphones at all
thx
it doesn't. those for whom it works are those using headphones with a mic, those for whom it doesn't are using headphones or cable without mic.
well, crap

It is a kernel issue. We are looking into it.
The funny thing is when I first flashed obsidian v2 I attempted to try out the 3.5mm out thru my car speakers. I was listening to Pandora in my car, I received a call and I heard the caller thru my car speakers. But it has not worked since then. And all I'm using is an audio out cable attached to my Alpine head unit
This does not work on any Froyo Roms, because of the required external mic, but does anyone know of a 3.5mm adapter that has a jack for headphones as well as a inline mic? Would this work ?
EDIT:
Looking at the audio routing from this page: http://developer.android.com/reference/android/media/AudioManager.html
it looks like some of it is deprecated, does this mean that it will never work?
int ROUTE_EARPIECE This constant is deprecated. Do not set audio routing directly, use setSpeakerphoneOn(), setBluetoothScoOn() methods instead.
int ROUTE_HEADSET This constant is deprecated. Do not set audio routing directly, use setSpeakerphoneOn(), setBluetoothScoOn() methods instead.
int ROUTE_SPEAKER This constant is deprecated. Do not set audio routing directly, use setSpeakerphoneOn(), setBluetoothScoOn() methods instead.

I see. Well I hope there's a solution soon, in the meantime keep up the great work u guys are doing for us.
I'm having a hard time understanding what everyone is saying is broken here...
I use a standard line out cable from my headphone jack into the analog aux input on my car stereo. I purchased a cheap extension cable that has the 3.5mm plug on one end and a mic/button at the other end that I plug the regular cable into. When I get a call, I pick up the mic on the cable and speak into it and I can hear the caller through my stereo and they can hear me just fine. This has always worked for 2.1 ROMS and so far has worked for three 2.2 ROMS I've tried.
Everyone is saying that the mic function is not working, but it's working fine for me.

It is working for you because of your extra external mic, it is confirmed a few post back that when using an external mic, it work fine but when using just a pair ear phones + internal mic (the one at the bottom of your phone), it fails to work. It used to work on 2.1 roms.
same thing here, went from fusion 1.1 to V4 Onyx...big pain in the ass out on the road today. Never wold have thought to check for that. I constantly have music going, ussually it will pause my mp3, and beep and show up the phone call, but now music plays, until I anwser and no go from the headphone jack.. I have mine hooked to an fm transmitter so i can take calls over car speakers.

Ah. That makes more sense then - I thought people were using the mic built into the headset, not the actual phone.
d33dvb, the cable I use is similar to this one:
http://www.accessorygeeks.com/apple-iphone-maletofe-headset.html
It's an iPhone accessory, but works fine with the Vibrant. It's been a few months since I bought it, and don't remember where I got it, but I do know that I got two of them for less than 8 bucks.

Thanks man, I think I will hit the best buy and that will be my temp solution to running 2.2
This issue is the biggest reason I'm not running a 2.2 rom.
What's the quality of the mic like on that adapter cable? The mic built into the phone is really good, I was on a call one day and had only raised my voice a little, but the caller on the other end asked me to stop yelling. I was like "Umm... I'm not"

[Q] Problem with Ear Buds.

Hi Everyone...Question where is the code behind the earbuds? Reason I am asking is that I plug my earbuds in and I can hear just fine but the person on the other end can't hear me. If I set TTY to VCO it works but audio stinks. Is this a Radio/ROM/KErnel issue??? Or do I need to unroot and take it back lol...someone please let me know!!!
Thanks!!!
it can be either or...
i found when using some AOSP roms(mainly older versions of CM7) people had a hard time hearing me.
currently i'm using CM7 1.6.1 and that's not an issue anymore.
In case anyone sees this it was actually a hardware problem, got a replacement phone and used the same ROM/kernel and all worked perfectly...the tech said that the saulder connections on the ear buds goes out easily...

Having a similar issue with ALL types of wired headsets. Posted in the General section and hoping to get some devs attention in it. Did some general Google searching and apparently by manufacturer design (thanks HTC!), when headsets are plugged in (not headphones mind you, diff is if it includes a mic), the mic disables on both the phone and the mic in your chord. You can bypass the disabling of the phone mic by changing the TTY mode but the quality is poor and still does not allow you to use your headset mic.
If you use regular headphones, the phone will show the headphone icon (again, not the headSET icon (with the boom mic in the pic)) and you can still use the mic from the regular phone. The problem I have here is it still requires me to walk around with my phone in the air as if it were on speakerphone.
I'm assuming devs can tweek this and I am 99% positive, previous headsets with my TB did NOT have this problem. I've used a mix of GB, AOSP, and Froyo roms (current), and have NOT found a way to get my headset (with mic built into the chord) to work. Extremely frustrating.

External microphone for hangouts.

Has anyone had any luck, or even attempted, using some sort of compact, external microphone for Google Talk or Hangouts? I tried searching but all of the threads are a year old, full of misinformation about how the 3.5mm jack is "out only" or involves soldering and magic.
Id really just like to know if I could throw in a non-powered or battery powered (gotta be small) microphone and have someone actually hear me when chatting. Right now everyone struggles to hear me when the tablet isnt 6" away from my face.
A directional mic that would allow me to set the tablet on a table (standing in its case of course) would be excellent. Small and reasonably priced would be great because the purpose is to use it on the road.
TIA
3.5MM port works with my Turtle Beaches with magic (Till I broke it...)
USB works with more magic, you have to port linux drivers :/
Bluetooth is the Easiest and Best option. I'd definitely go bluetooth for ease of use and connect.
My $.02
I'm looking more for conference functionality. So I can have it sitting on the dining room table and have the girlfriend and I chatting in a hangout. I surprised this hasn't been addressed, I guess nobody uses their tablet for Google talk or hangouts.
I use the earbuds that came with my Nexus S, they have a microphone built in.
As far as stand-alone microphones, I don't know of any. If you find one I'd like to know!
Id think if that external mic plugged in works fine when a simple, stand alone mic would. But most of the ones on Amazon have horrible reviews. I was hoping someone had thought about having a group chat on the thing.
I tried one of thos bluetooth car speakerphones and it was horrible. That is going back.

you may want to try this http://www.amazon.com/Logitech-Boombox-Smartphones-Tablets-Laptops/dp/B005PUZOYM
its an external speaker with a mic built in. so you can set your tablet on the table and place the mic closer to you, its bluetooth so dont have to worrie about wires, i've used it for my phone streaming music and when a call comes in i can talk. . on my tablet i use it to play movies audio but never used the mic in that sense.
maybe that way will work for you
Any chance you could try a chat or hangout with it? Ive tried my existing bluetooth solutions and nothing works.
As for wired mics Ive tried multiple and all have failed. They dont record audio in any way well (camera, chat, whatever) and plugging a mic in tells the transformer its got headphones in.
Headphones for TF101
I tired the original headphone with built in mic which came with blackberry Bold 9700. It worked. Both audio out and mic is working same time.
Does anybody know if a USB mic would work conecting it to the dock? I stream video on ustream but built in mic is below average. I was thinking on buying a usb mic and conecting it to the usb ports. Will it work?

Depending on how much you want to spend and what converters you are willing to use:

**Headphone jack audio out (jellybean) solution here** (app)

for those of us that use our phones in the car as mp3 players, or connect our phone to an aux input to our cars or other piece of equipment were surprised to see that the new JB update killed that for us.
ive mentioned it in the bugs thread and asked a dev to see if he can remedy it.
until it gets fixed by a dev or google/htc/sprint i found a free app that will fix it for us.
and it does work.
google play search "soundabout"
make sure you check off wired headset detection, and select "wired headphones" in the [media audio...] selection box.
voila, you got sound to your aux adapter or for your car now.
the only issue i see is the builtin music player doesnt let you choose EQ and the beats options is still greyed out.
so you might want to experiment with other 3rd party music players with an eq if you want better audio.
:/ I've used viperboy's rooted stock JB and played audio out to my car just fine...
right now, im on the stock jb ota rom. and wasnt getting audio out until i installed and configured this app.
had audio just fine on ICS
posting this just in case someone else is having issues.
i wonder what viperboy did or configured in his rom to get it to work.
I'm on stock jb ota not rooted and audio works fine for me via headphone jack to aux port. My only problem is, when I'm plugged in my car and then turn my Bluetooth headset on, it switches my music to my ear piece. Not that big of a deal, I just unplug and replug my phone back in and it switches back.

I have Xperia TX and after JellyBean update, my Sol Republic headphones did not work at all. I installed this app and works like a charm. Thanks a lot.
Found a cure
Guys! I finally found a cure to this this problem.
It is caused by unbalance of the headphones...
Steps:-
1.Download Poweramp
2.Go to Equalizer-->Tone/Volume
3.Adjust the balance to Right--Full throttle(It really-really works!)
Now you can use earphones/headphones with mic.

[Q] Bluetooth to car stereo phone noise

Hi all. New here, so hopefully this will be concise enough.
T-mobile HTC Amaze 4g, no mods, all stock plus a few apps. Everything working fine on the phone. Purchased a Platronics BT headset, works OK; limited range, but passable. Just bought a Sony MEX-BT4100P car unit. Did the install myself (retired auto technician, so I know a little about doing it correctly). All working OK, BT pairs fine, functions all good (Phone book, redial, etc). Problem is a buzz noise during calls, only audible on the other end of the call, but it's pretty loud. Sound is similar to a slightly shorted mic cable. Voice is audible, just a loud background buzz. No noises with any other car stereo function. No noises with any other phone function.
Talked to car stereo vendor, they sent new unit and microphone. No change. Talked to HTC. They say that since the Plantroncs works fine, there's no problem with the phone.
I'm trying to find out if anyone else has experienced this specific issue and if so what had to happen to resolve it.
Any thoughts? I don't have another BT phone to try
Android 4.0.3, Sense 3.6. Don't know what other info might be helpful.
Thanks.

Hey Charlie,
I remember having a plantonics headset. They were awful for me and they broke eventually. Did you try another headset? I think the headphones you're using could be the source of the problem. Hopefully someone else experienced in BT and headsets can assist you.

The Plantronics headset is fine; it's the Sony car stereo BT function that's making the noise...
It's been a while since I've had the stock ROM on my phone, but try looking under the settings menu in dialer for 'noise suppression' and make sure it's ticked.
Does your head unit have a gain setting for the mic? I had a JVC unit that had one in the Bluetooth menu settings.
Actually, I just looked up your manual, you do have a mic gain.
It looks like you also have an echo canceller/noise canceller setting as well. See what playing with those do for you.
Failing those options, it sounds like you have interference in your mic. Try routing it away from any wires that carry current. You might try just holding it out in the open and making a test call.

Head unit - I've tried all settings on mic gain and noise cancellation with no changes at all to the noise, although voice quality changed as expected.
Microphone has been pulled out of the car, literally to the full extent of its cable, with no change. I've wrapped the mic and its cable in tin foil and jumpered that tin foil shield to chassis ground with no change.
It does indeed to me sound like microphone interference, but nothing I do, including a different mic, changes the noise. Head unit and mic have been changed out for new.

Follow the path, eliminate as you go.
1. Unplug the mic completely. Make a test call, see if your caller hears the noise still. If not, it's either the mic (replaced already, but not unheard of to get multiple bad ones. Try a desktop computer microphone?) or poor shielding in the radio (not easy to fix, even harder to locate.) If it's still there....still might be shielding in the head unit. Unlikely though.
2. You've already messed around with the head unit's settings. Nothing to do here.
3. Bluetooth. My radio used a USB bluetooth adapter, yours is built in. Can't try a different BT.
4. Phone. You don't know someone with a phone with bluetooth? If pairing with a different device results in a clear call, it's the phone (you could try rooting/updating/replacing it. Maybe they just don't like each other?) If the noise is still there with a different phone, it's either the head unit (you got another bad one or they just don't make them very well) or it's outside your control. Maybe the tower itself. You could try driving quite some distance away, till you're on a different tower. See if it's clear then.
Beyond all this, I really don't know of anything else to try, apart from getting a different head unit.

This tells me it's not interference, at least not from the car's electrical system. Do you happen to live under high tension lines?

I did try unplugging the mic and the noise goes away, but according to Sony and the vendor, if a mic isn't plugged in, the entire audio chain gets muted automatically, so it's not much of a test. I'm going to see if I can dig up another mic like a computer mic with a mute or on/off switch and see what that might do.
I'm in a rural area and not too many cell phones I can borrow here. Might be one I can find...
I'll try another tower too; that's something I have not tried. But this really sounds like audio input chain noise rather than post-processing noise. I was an audio engineer in a previous life and I am still leaning towards mic-related issues...
Thanks.

Update... Tried driving to another location, and voila! The noise disappeared. I'm now getting normal audio from the system. And what's really strange... back at the house the noise is gone as well...
Thanks to all for the suggestions and ideas! Glad it wasn't something more difficult to fix...
