Develop Bugs

[Q] Sound stuck in earpiece after disconnecting bluetooth headset?

I've used many ROMs (Viper, Bonsai, Nebula, currently ACS Syndicate) and I've had this problem on all of them. I've even ODIN'd back to stock before and it still didn't fix my problem.
After disconnecting my Epic from my Jawbone Icon headset, the sound often gets stuck inside the earpiece. Music, movies, games, ringtones will all play from the earpiece instead of the speaker behind the phone.
Is there some software fix to correct this? Can any of the devs point me in the right direction as to how I might troubleshoot this (maybe at the kernel level)?
Thanks in advance!

This doesn't really go in Development, and I suspect it will be moved soon.
I can tell you, though, that I've experienced similar problems, intermittantly, and here's what I've observed.
If I'm listening to music through bluetooth, before I disconnect, I'll stop the music. Then I'll turn the bluetooth device off. Then I'll turn bluetooth off on the phone. If I do it in that order, I don't seem to get the bug.
If you do still get the bug, rebooting fixes it.
Hope that helps!

This is a known issue. It's a bug that has to do with being connected to a device for both media and phone calls. If you use only one or the other it doesn't happen.

It's very annoying for me as well.
The other bug that I noticed is after taking a call over BT, when I end the call, the earpiece on the phone starts randomly popping. rebooting fixes it but it still really irks me.
I think the OP is wondering if there's a way to dig around in the BT stack and fix it ?

This stuff has been going on since DK28 and before. I believe Rodderick was looking into fixing it from the kernel side, but I'm not sure how much progress has been made. I know it's not as bad as it was on DK28, but still very annoying. It used to happen to me all the time (audio going through earpiece instead of speaker after disconnecting Bluetooth) when I would turn my car off and it would disconnect the Bluetooth to my car stereo. Now that I have the Samsung Car Dock, I just connect Bluetooth for phone only, and use the audio out on the Car Dock for Navigation and Media.

Moved to Q&A.

i am having a simular issue but mine is that when i connect to bluetooth headset i have to have media playing before i get a call or i will not hear the other person in the call.
it seems to me that ANY bluetooth headset with A2DP is doing this and i have tried 3 diffrent headsets. Jabra Stone, Jawbone Icon, and the Blueant T1.
all 3 of these headsets do this. does anyone have any solution yet?

Even if there isn't a fix, I wish there was an app to reset the sound settings post facto. Anyone know of one?

I just want to add my name to the list of those who are affected by this. Glad it's not just me, though. Hopefully it can be debugged easily.

For the record, a Quickboot Hot Reboot (reboot of Android only, not phone) does NOT solve the issue. Only a full reboot works for me. Seems like it may not be a software issue but something hardware-related.

Just want to add this happened to me the first time just now. I'm on rooted EC05. I was scared for a bit that the speaker had blown. Then when I discovered it all coming from the earpiece, I remembered this thread. A reboot did make it go away.
I wonder if it has any relation to the issue I see once in a while since the upgrade where my BT devices need re-pairing and ask for a passcode, when they really shouldn't.

I Also Have This Issue
I have had this exact issue since DI18.
After I hang up a Bluetooth call, I have popping sounds coming out of the earpiece. Turning off Bluetooth doesn't fix it. Turning Bluetooth back on after turning off doesn't fix it. In addition, after this happens, all devices sounds (phone ranging, notifications) all come through the earpiece and *not* the main speaker.
I've had all of the stock ROMs up until EC05 loaded on this Epic and have had the same issue throughout. I am now running midNIGHT ROM, which has cured most problems I’ve had with my device, except this issue.
I was just poking around trying to find some sort of tool or the name of the service(s) that I need to restart to fix this issue.

Same issue for me. Quite annoying as I listen to audible over bluetooth quite a bit, and then pretty much know I have to reboot when I turn bluetooth off.

SRF users have reported Bluetooth issues being cleared vs. stock builds. I can't say exactly why, but it does seem to work.

What are SRF users?

Nope...
Syndicate Rom Frozen...
Well, I'm on SRF 1.1.1 and I've got the same incredebly annoying audio issue.
Please, someone, come up with a fix!

Constantly losing Bluetooth when A2DP triggers

I have a Bluetooth headset that supports A2DP. All notifications and media play through it automatically, which I very much like. It worked perfectly on my OG Epic 4G, but on the Touch I've had constant issues where somewhere around 25% of the time that my phone sends it something via A2DP (usually a notification sound) my Bluetooth will disconnect, I'll hear its disconnect sound, then I'll have to wait a couple of seconds to hear it reconnect, which it succeeds at roughly 80% of the time. Otherwise I have to turn it off and back on to get it to connect.
Anyone else experience the same with theirs? Any thoughts on a cause/solution?

Are you rooted? What ROM are you running?

While I am now rooted, but otherwise stock, this problem has occurred since day one. It's not related to any customizations.

Am I REALLY the only one experiencing this? Seems surprising.

No. I thought it was my headset, and I was about to replace it.

All right, so we've got one more person with the same issue. Now if only we had some extra thoughts on a solution, or a line on this being something Samsung is aware of.

Since this got moved I'm not sure if it's been seen in this forum. Anyone got any thoughts? Similar experience? Idea of if there's a possible fix?

I'm have a problem playing bluetooth audio through my factory stereo
I'm have a problem playing bluetooth audio through my factory stereo, which worked flawless with the EVO. This is a show stopper for me because I travel a lot and listen to podcasts in my car. Since I got the E4GT I have been unable to stream BT audio.

I wouldn't be at all surprised to find out this is related to the same SoundPool bug that causes a lot of games to crash on the E4GT. I have no further info to help you, unfortunately; you can Google around about that. The short version is that that if it IS another symptom of that same bug, there's probably no fix.

I have a tiny Bluetooth USB jig that I plug into my laptop and my music plays fine through my laptop. I will test it out over a longer period of time tomorrow but so far its been great..

[Q] Broken Internal Microphone MOD Request

Hi all,
After an extensive search around the web and these forums I have not found a solution to my problem. In a weak moment, I spilled a small amount of water on my Verizon Galaxy Nexus and my internal microphone was broken as a result. The broken microphone left me with a horrible static sound during calls and the person on the other end unable to hear me. However, when I use the phone on speakerphone, calls work fine. I'm assuming this is because the speakerphone uses a different mic (i.e. the camera mic?). I've thoroughly tested to make sure that the microphone is broken by wiping completely, going all the way back to stock 4.0, and checking the microphone on each of the following iterations of Android. I went to Verizon and had my SIM card swapped out to no avail. After the problem failed to fix itself, I re-rooted and am now running CM 10.1.
Anyway, as a user of Groove IP for my calls, I started messing around with the settings and found that it allows me to change the default microphone during calls. It allowed me to force the phone to use the camera mic rather than the internal mic and, alas, it worked! I'm sure the quality on the other end is not quite as good but it's the best I'll be able to do at this point. Now, here comes the MOD request.. I'm wondering if any of the amazing devs that frequent this forum could take a look through the source code and see if they can force my phone to use the camera mic all the time (via a flashable zip?). This would allow me to use it not only during calls but throughout my system as well (i.e. voice search, text to speech). This would really extend the life of my device and I'd love to buy somewhere a beer or two for helping me out.
If you want to see how Groove IP does it, the mic source settings are in Groove IP (lite or pro) troubleshooting section of the settings. Thanks in advance!

Im preety sure thats a software glitch you have there my friend the speaker and normal phone use the same microphones as far as i am aware. The reason it may work in speaker phone only is because the galaxy nexus has a microphone on the top and bottom of the handset. Which mic is not working. I need specifics.

Hmmm... Okay, I didn't know it uses a second mic other than for noise cancellation. I was assuming it was the bottom mic, and I test it by using the Sound Recorder app and all I get is static. I can record videos with audio just fine, which is how I know the camera mic works. It would certainly be a curious software issue, considering the problems occurred immediately after the water damage, but I'm open to it. How do you think I can test the different internal mics to see which one is/isn't working?

From what I know now it sounds like a hardware issue. I highly recommend buying a replacement. Im not quite sure what youy expect from a mod or something. Could you explain. Ill try to help as best I can.
p.s. also I just posted my new project HERE for the galaxy nexus and im not sure if the download link works for anyone but me on my google drive. would you mind at least testing the downlod link for me? Thanks!

here this might help: replacement mic

Well that replacement mic could certainly be an option, I appreciate the link. I can also confirm that your download works as well.
But what I'm looking for is this, some sort of mod that will deactivate the broken (internal mic) and tell the phone to automatically use the camera mic in all situations in which a mic would be needed. Basically tell the phone it only has the one mic. I'm not sure if this is possible or even plausible, but I appreciate your help either way.

You will need a special sort of mod. Im not sure if there are any out there. I could take a look into making one for you, if you like (no garuntees).
P.S. Thanks for trying the link.

Anything you can do would be greatly appreciated.. Even if you get in there and decide it's too much work, that's fine. If it won't work then maybe I'll try that replacement mic, though I'm not sure I have the steady hands or the technology to pull off a job like that.

You can replace the mic for under $15 so it isnt too bad price wise. Do a google search locally for computer or phone shops. You can often time get them to replace it for like $50, but its garunteed to be properly installed. Doing it yourself isnt very hard if you have a good instruction ste and the proper tools.

Yeah, that would definitely be better than getting a new device before I'm ready. Thanks.

So I replaced the USB and mic to no avail... The same problem persists. Major static on phone calls until set to speaker phone and nothing but static recorded with the sound recorder. I suppose it's a problem with another piece of hardware or actually a software issue. I've rooted, un rooted, wiped, and wiped some more, so I'm suspicious it's a hardware issue.
Is it possible or even plausible to make a (flashable) mod that tells my device to only use the camera microphone (or the other mic?) for all situations in which a mic is required? I'd be willing to throw a beer or two (or whatever your poison) your way as this would really extend the life of my device.

I have the same exact issue!
I've been looking everywhere for the past month to find anyone else with this problem... I can't believe i missed this post somehow. For me it started after i put my head to my phone after a shower. I wasn't sure it was from this as i had recently started using a new ROM as well as an extended battery from Hyperion.
I have attempted replacing both the headset speaker ( the one used when you put the phone to your ear) which includes the second microphone and that didn't help, and i just tried replacing the microphone and that didn't help either.
I have also attempted going to earlier ROMs and that didn't help.
I have been wondering if flashing a different radio may help, though i figured it probably is not related to the radio as the calls sound fine on the speaker mode. Have you discovered anything else with your phone?

Unfortunately, nothing has changed. I've accepted the fact that I can only use my phone on speakerphone. The most disappointing part of it is that I can't use voice actions on my phone.

I should also note that since I first notice this issue, I also noticed my phone slow to detect the charger after plugging it in. Instead of it being to charge almost immediately after plugging it in, it take about 10-15 seconds before it detects it. This problem persisted even after replacing the micro usb component.

[Q] Odd bluetooth and speaker problem

I have a samsung g-S2 (r-760) and installed the pacman rom along with the ACPverter-v1.0. I set up the rom and everything was fine except the bluetooth and the speaker. The bluetooth I have is a plantronics pro plus. The odd thing is that when I use the bluetooth I can here all my music but when I go to make a call I can not hear anything. The person on the other side can hear me just fine and the speaker does the same thing. If I disconnect the bluetooth and use the phone and select speaker - nothing comes out. The phone works up to your ear. I use odin to go back to stock fk19 and it is still doing this. Like a dummy I did the same thing to my wifes phone thinking it was just mine. Same results. Can anyone point me in the right direction to get this solved.... Thanks in advance.

The speakerphone issue is already a known problem with AOSP-based ROMS. No idea about Bluetooth as I have it working on my end.
It's rather odd how the speaker / bluetooth still is an issue after ODIN back to stock.

Mic volume issue after EU OTA

Hi all,
Quick question, has anyone experienced issues with the microphone while using Skype or Hangouts after the latest (last week's) OTA for Europe?
At first I thought it was bad design on a case I got, but the issue persists even without the case (and there actually is a hole in the plastic for the mic), tried Hangouts to make sure it wasn't just Skype, so I'm thinking it might have to do with the OTA update.
The mic wasn't doing wonders with capturing before, but it appears to be unusable for Skype now unless the tablet is held at the same distance as a phone.
On a relevant note, is anyone aware of any tools that could help adjusting mic gain or disabling the automatic gain control/ noise cancellation features?
ROM is stock LG, rooted.

Me too
Same here with the exact same setup.
I've tried alsamixer but this proves useless until you know witch setting is involved among hundreds of available mixers.
I wonder if an external bluetooh or USB microphone is not a better option.
EiZ

Same issue
I just recently got the G pad and I definitely have a problem with the mic. Is this happening on all the G pads or do you think is a hardware issue on my device?
I tried with Skype and Hangouts and my voice was barely audible on the other end. Just to make sure it was not my internet connection I tried with my old trusty Galaxy S2, no problems there so it is definitely a problem of the G Pad.
I have no screen, warming, yellow lines, light bleeding or any other issue. So, the device is perfect except for the mic, do you think it is worth to take it back to the shop to exchange it for a new one or this will not cure the mic problem?
Any luck tweaking the mic in software btw? Finally, has anybody tried to use a bluetooth headset and microphone with it, is it possible?
Thanks!

I am also having mic issues currently on sw ver v50010a.
it seems very quiet. update is downloading so will see how it compares.

I'm on software ver V50010b and I keep having issues with the microphone.
Don't know what to do... the rest of the tablet is perfect, so I'm afraid to exchange it just for this issue and get a new one with more problems.
