[Q] no sound on calls: hardware or software problem

My Samsung T989, which was running Cyanogen 10.1.3, recently starting having the problem where I wasn't getting any sound from the earpiece during calls.
Speaker phone works, headphones work and the person on the other end can hear me (so microphone works). But nothing from the earpiece.
I've tried every setting but nothing. I've also tried Cyanogen 11 just to see if perhaps it was a bug that has been fixed, but still no sound, so I assume that this is a hardware problem.
Is there any way of diagnosing this better as either hardware or software? Any known fixes?

WTF is the deal with AOKP 10.1 MR2 and Sound

You are not the only one. Mine the sound other than calls is GONE! I am trying to figure this out. Tried to Flash the ROM from a clean flash with reset to factory and the works and went directly to AOKP ROM Directly with the latest Gapps. No dice. The phone ear piece works but speaker phone and any thing else via the speaker does not work any longer. I am dead in the water here and need a fully functional phone.
This is not my first rodeo. I have flashed many Andriod devices, Cliq+, Nexus S, Nook Color, Acer 500 etc... and the Galaxy S II.
Heck I am also now having issues with the CWM Recovery as well. I can not flash it current. The CWM ROM Manager says flashing and never completes. It has Root privileges. Really has me beside myself at the moment and it is my primary driver so it is interfering with WORK now and really has been ANGRY!

Maybe try out different radios or make sure you using the required version of TWRP?
I'm using UVMC6

[Q] No sound from any device output, other than bluetooth-connected device

Having an issue with no sound emitting from any audio output on the phone, but sound will play through Bluetooth-connected device. No sound from front speaker (phone calls, dial pad), no sound from rear speaker (notifications, ringer, alarm, media) and no sound from wired earpiece/headphones. Seems like it's stuck in Bluetooth/headset mode, but turning off Bluetooth doesn't restore sound. Problem is intermittent, haven't determined pattern to the behavior.
Phone was rooted long ago but kept stock ROM. Flashed Paranoid Android 3.99 RC2 about a month ago, and problem seems to have started shortly thereafter, but not sure if related. Haven't tried to reflash.
Any suggestions? Tried searches, but didn't locate this specific issue.
SGH-T999 (US/T-Mobile Galaxy S3)

Is it a T999 or a T959? And flash back to stock.using Odin. If it still is a problem it's likely hardware related.

Sorry, phone is T999.....got rid of the T959 long ago, but must have been stuck in my head.
Will reflash this weekend and hope the sound issue is resolved. Thanks.

Did some more investigating last weekend before flashing ROM (never did the reflash).....seems that often, not always, if I turn off the car ('13 VW) while still connected to phone Bluetooth, the phone's sound quits working (all sound). Rebooting phone and turning off Bluetooth does not restore sound. The only solution I've found is to reconnect to car's Bluetooth, then turn Bluetooth off before shutting down car, and that only works about half the time, but sound is instantly restored. My estimation is that this wouldn't be hardware related, is that a fair assumption?
I also have a Tasker profile set up on phone to disable PIN lock when phone is connected to Bluetooth device (enables Sena Bluetooth headset used with motorcycle helmet to function properly), could that be causing the problem? Anyone else experience this issue?

Please try another Rom. Some of the Custom Roms may not be uptodate with CM Checkins. This issue was reported a bit back. There were CM Code Fixes that may not have been incorporated in that rom.
I am using Slimbean 2.0 (Android 4.3.1) and have seriously tested its bluetooth capabilities.

its also been reported thst msny car manufacturers did not bother to put any time or money into their BT capable systems. they just threw it together so they could add to feature lists.
Lots of peopke have problems with BT in the car, especially on cm roms. but those are notorious for BT issues to begin with.

Thanks for the replies. I flashed to Paranoid Android 3.99.1 RC1 but the problem still exists. I never had this issue with any of our vehicles, until switching to PA from stock ROM. If problem becomes unbearable, may go back to stock. Thanks again.

@yardsale
I should have mentioned in the previously. Please read this post of mine. Yes its a different Rom. However, here primarily the issue is that of hardware antenna of the T999 talking to the Car's antenna. Doc is 100 % correct, the manufacturers do use substandard Antenna. On that thread, someone else reported issues with two '13 VW for themselves and their brother's.

Bluetooth no longer plays music through headphones, but calls still go through

Hey guys,
So okay, I am having an issue and have not been abe to solve it for a week now. Allow me to start...
I have the sony MDR-1RBT headphones. I've had them since last February and have used them without any problems. Connection, set up, and usage has always been a breeze. Until recently.
I started my day and connected my headphones like usual and it said they were connected. Cool. Went to play music and it played through my phone. Not sure why. Tried to make a call, audio went through bluetooth device. So they say they are connected and playing through the bluetooth device but is clearly is not.
Things I have tried to fix it:
power cycling phone and headphones
disconnecting and reconnecting bluetooth connection
gone into device settings and made sure media was checked for my bluetooth device
researched through the internet
followed what the person on this link suggested: http://forums.androidcentral.com/ge...r-playing-note-2-music-but-does-do-calls.html
The last step, when I tried it it connected! Yay! Then I turned the headphones and bluetooth off and went to turn em on again and it went back to not working. Tried the same method and it didnt work.
I am running on an LG G2 Rooted but not ROM'd. I know the issue is not with my headphones because I tried to connect the device to my Jawbone Jambox and it did not work on that either. I am not sure why it is not working.
I consider myself pretty tech-savvy and I am pretty upset that I haven't been able to figure it out. Let me know what you guys think.

When you go to your phone bluetooth setting with a list of paired devices, do you see 1RBT listed in there as "connected to phone and media audio"? This is very important because it sounds like it's only connected to phone but not media audio.
Do you have any other bt devices you paired up with your phone? Like wireless speaker or another set of headphones? Quite often if you have a few with power, there will be a race condition which one gets connected as media. But since you said music was playing through your phone speaker, I assume there is not conflict with another device. But nevertheless, just delete all your previously paired up devices in Bluetooth list to make sure there is no conflict. Remove 1RBT as well. After you remove everything, reboot the phone, and do a fresh pair up with 1RBT. See if that helps?
Also, try to pair up these headphones with another device, either phone or a tablet to make sure there is no issues with bluetooth radio on your phone. If you have access to another bluetooth device, try to pair it up with your phone to make sure everything is working as expected.
Let me know the results, and we will go from there.

my device is rooted. i did a factory reset but the problem remains unfixed. please help. i have installed g3 tweaksbox but i dont see any mods that is related to music apps. i dont know what to do. i have considered unrooting and flashing stock rom.

I was having the same problem until I realized the volume on my jawbone itself was turned down.

Vectron's Suggestion Worked For My Bluetooth Headphones
I was heaving the same issue as the OP all morning. My Beats66 Bluetooth headphones were working just fine since I got my Alcatel Idol 4, with Android 6.0.1 (Marshmallow) phone through wireless provider CricKet, just 2 days ago. I primarily purchased the headphones for placing phone calls, just because most Bluetooth headsets I have purchased, and Android phones in general, are too low volume for my impaired hearing to make out. However, I do listen to music on them as well.
This morning as I am exiting a taxi, I hear music coming from my backpack. Somehow, something launched one of my music apps, probably the buttons and screen were activated while items in the backpack pressed against them. The settings said Media and Phone were connected to Beats66, and the phone did come through the headphones only, but the music would only play on the phone's external speakers.
I found this thread from a Google search, and Vector's post was helpful for me. I went to Bluetooth settings and highlighted Beats 66 headphones, then selected "Forget." I rebooted the phone, paired the headphones, and all my music apps play through the headphones now. Lets see how long it lasts right? Since this is a brand new out of the box phone, I did install numerous Apps, all of which want user authentication, permissions, and countless settings and permissions to interact with other Apps and phone hardware. Hopefully with everything getting set up the way I like my phone, (I'm particular about everything, or I just find the phone annoying rather than a tool), I won't make anymore changes that will alter the operating status of the headphones.
Thank you

I am experiencing the exact same issue on my LG G3 with my Skull Candy Wireless headphones. The headphones pair and phone audio works, but Pandora, Google Music and any other streaming audio app plays over the phone speaker. I noticed that I received a Carrier OTA software update on Jan 17, 2017 and am wondering if that is when it may have charged. The only way to resolve it so far has been to clear the BT cache. This is temporary fix as when you attempt to pair again it is back to only phone audio and no music audio.

My headset is not working with music until you turn off the phone audio just to play music. My phone is Lenovo A2010-a and my headset is Nia X2. Please help

Ever get this resolved? Still having this issue and so far only fix for me has been using Ti Backup to nuke all the bluetooth data, rebooting and then it'll connect fine. I also have Skullcandy BT headphones. Trying my car's BT too to no avail. Same problem. I think this is the same issue: https: //forum.xda-developers.com/lg-g3/help/bluetooth-calls-media-audio-t2837471/page4

I ended up buying an Amazon​ Moto G4 as it is slated to get Android 7.0. I honestly believe it had something to do with the last security update LG pushed out. Since the G3 is not updating I will attempt to root and rom at some point though recent search seem to show the LG G3 can't be rooted.

I rooted mine fine with Kingroot. Get Kingroot, root, install twrp and flash supersu then delete Kingroot. Worked for me at least.
As far as this BT bug with the G3 I don't have anything better than the data wipe workaround so far, so good luck with the Moto.

Thanks guys. I also had the same problem but i restarted my phone and my music is just playing. Yah!!!!!!!!!!

Headset mic stopped working/barley working. Software issue.

Hello everyone,
My LG G3 is giving me a hard time, when I connect a headset, its microphone isn't working or it does but it's barley audible compared to the device's own mic.
The headphones part is working as usual and when the headset is connected sounds goes only through them like it should.
I've started using this headset a few days ago and it worked like a charm but then it's suddenly stopped working like it had been.
Fortunately I have another LG G3 on hand, so first I checked the headset with it and it works perfect.
So then I've replaced the 3.5 audio jack from the other G3 into my own to figure out if it is causing the problem and it is NOT,
since I got no improvement in my own phone and I also put MY jack in the other G3 and it worked there flawlessly with two different headsets.
I've been trying to record into / monitor with two different apps (lg audio recorder and another another one).
I've killed all apps running in the background. I've restarted numerous times, ran CCleaner to clear cache memories and whatever.
At one point a few days ago, maybe it was just before it started (and this might be a clue) the "plugged device" icon or "headset" icon on the notification bar stayed even after I've disconnected the headset and I think I needed to restart the phone but if i'm not wrong the headset kept working after that.
I was trying to find any kind of audio service to restart or anything like that but I didn't find any, I just killed them all to see if it helps.
I've also tried using "soundabout" app to try to force the audio path to the headset and played with some settings but to no avail (I disabled soundabout service after that attempt).
Right now I see no other option but a hard reset and I'm pretty sure it will solve the issue. but I hate going through backing up and restoring everything. and even so, who said this issue won't happen again? I've tried to search for an answer but found nothing like my problem on the web.
I just read something old from 2013 that mentions a bug in android audio. not sure it's related. something about "AudioPolicyMangerBase" (it seems I can't post links yet) from an app that had a switch to switch between headset mode or phone mode. but in any case it's no longer maintained. again, not sure it's related.
Update: Now I got no sound with two different headsets on the SECOND LG G3 as well. it seems messing with it around, plugging and unplugging messes with it's software somehow and maybe it locks the audio route in a way that it's can't work.
Any way to reset all audio ins/outs routes in the device?
I'll appreciate your help. Thanks a lot!
Roy.

Headphone Sensitivity Problem

Over the past several days I have encountered a serious problem whenever I try to use headphones with my Mi 6. When I have a headphone plugged into the audio USB dongle and attempt to play music, at the slightest vibration, tracks will start and stop playing, tracks will change, the volume will shift, and the microphone will activate. This has made it almost impossible to listen to music with the phone anymore. I have tested this with two headsets, which both cause the effect, though it does not happen if I do not have a headset plugged in. Because I have had this phone since soon after it was released, my guess is this problem was caused by a recent MIUI (I'm on 10 8.10.11 Beta) update. It kept occurring even after I installed Blackplayer and tried using that instead.

It sounds more like a hardware problem to me, dirty or loose connections

I tried cleaning everything as best as I could, but to no avail. Does anyone else have any experience with this problem, or is there a way I could disable the phone from accepting input from the USB port so that my headphones will be usable?
