Yesterday I decided to try a couple of custom ROMs, and after setting them up completely I realized that the mic in my Bluetooth headphones didn't work properly with either of the.The volume captured by them is waayyy too low and the other person can almost never hear me properly.
On OOS stock and beta, the sound is crystal clear and the person can't discern the difference if I am using the Bluetooth headphone or the phone itself. I have also verified that I am indeed using the headphone mic and not the phone's inbuilt mic.
Now, I have reverted back to stock OOS and it's back to normal.
I flashed HAVOC-OS and AOSiP ROMs.
I hope there is an explanation for this issue.
So it seems like Omni and ROMS based on it have it working correctly. I have deduced as much as that it is not related to the kernel.
I am guessing that it is most probably related to the specific device sources or Qualcomm sources used.

THE PROBLEM:
The internal microphone does not work for call audio unless I plug in headphones. The same applies to speakerphone mode.
My Bluetooth headset works fine, as do my old iPhone earbuds with built-in mic. In both cases, their respective external microphones were used and functioned appropriately.
The issue seems localized to the Phone app. The microphone works fine in Sound Recorder as well as dB Level. At first I suspected a faulty headphone jack, but I've installed SoundAbout and it properly detects when I plug in or remove my headphones.
THE BACK-STORY:
I've had been running CM9 RC2 on my phone for some time now, and decided it was time to check out CM10. I flashed the 3/04/2013 CM10.1 Experimental M2 build and got hit with the call audio issue. I used roger_n's unofficial ROM for a few days and subsequently updated to the 3/25/2013 CM10.1 nightly. I've pretty much had this issue ever since then, and I never had any issues prior to flashing CM10.1.
I've tried going back to CM9 and also upgrading the radio to UCLF6. I've done a full wipe and formatted /sdcard.
Can anybody offer any insight?
Odin back to stock. See what happens then.
Hello there!
Recently I have encountered a strange issue with the wired headphone stereo balance. The volume on the left side is as expected, but audio on the right channel is all but inaudible. It´s there, but extremely quiet. If I set the volume to maximum, audio on the right ramps up to being listenable (with what would usually be a low to low medium volume setting)...while the left is blazing like crazy, of course.
Using a stereo test MP3 (ping pong sounds, basically), I could verify that the channel seperation is correct, just to rule out that it´s a headphone jack/plug problem (i.e. the plug making no contact with the correct connectors inside the jack). Or, to put it simply, both audio channels do indeed get to the correct side of the headphone, just not enough on the one side.
I have no idea what could have caused this. Stereo balance was definitly working correctly the one time I tried wired headphones on the stock ASUS ROM, way back before I unlocked, rooted and installed custom ROMs. I haven´t tried it since, until a couple of days ago and that´s when I noticed.
Things I´ve tried since then:
- Dozens of different headphones, headsets, adapter cables. All show the same problem.
- Tried to clean out the headphone jack as best as possible.
- I even filed down the tip of one plug a bit to maybe get a better connection, but the connection itself doesn´t seem to be the problem.
- Factory resets, full wipes, different ROMs (stock, CM, CROMi).
- Different audio DSPs.
- A LOT of audio related apps (Volume+, EQs...)
- Audio players with built in balance control. These do indeed shift the stereo image to the right side, but don´t make the right channel itself louder, which results in a very quiet, kinda mono-y, hollow-y sound at normal volume levels.
I am assuming there is a hardware problem, and I assume it´s not the headphone jack itself, but something else in the circuitry.
I really, really, really don´t want to RMA the thing, since it took me *weeks* of discussion with ASUS support to get it unlocked in the first place (wasn´t able to, due to the infamous MAC/server mismatch thingie), and I don´t want to get it back with a new mainboard and perma-locked.
So, my questions are: What else can I try? Is there a way to boost the one faulty audio channel? Maybe by editing some system file or writing a script or something?
I´m unlocked, rooted and running CROMi-X 4.3b4 now (which is going to be great, once it matures, btw).
Thanks!
So I've made a couple posts about my problems with bluetooth audio streaming, but I have a bit of a different question this time. I have been trying a multitude of AOSP roms (4.1, 4.2, and 4.3) trying to get my bluetooth audio to work properly. I have had no luck, the audio is super choppy and distorted.
Recently I tired the Eclipse 5.1 ROM which another user told me specifically his bluetooth audio streaming was fine (on the same model phone!). I did a 100% clean install, I wiped everything, including internal & external storage. I tried fixing permissions (which he said he did to get it to work), and nothing. I still get choppy audio over BT. Does anyone have any idea what could be causing this? What is there beyond the ROM that would affect BT?? I even tried CM 10, which is 4.1 (a version with the old BT stack implemented) and still got choppy audio!! The only thing that seems to work for me is TouchWiz roms.
One thing I notice, and I'm not sure this affects anything, is when I boot into download mode in the binaries line it says "(3 count)"
If anyone has any light to shed on this it would be awesome!
Thanks so much.
there is no sound getting out upon connecting the headset.
tried on my Nexus, everythings fine.
any help?
edit: stock rom, stock kernel. device rebooted couple of times, sound is all right without the headset.
tried the trick with half way connecting the headset, didnt work.
i do have the same problem with my Apple Ear Phones, its basically a different technology behind it. after that i flashed a custom rom (crDroid) and wola....they are working!! (but not the microphone sadly :/)
try flashing franco kernel as it has newer audio / headset commits. it may fix your problem.
Hey guys,
the OP6 is one of the best phones I had yet even with the stock os. But even before returning to stock I used Havoc OS. There, I didn't have any problems that couldn't be fixed in the settings. Now when I have a bluetooth headphone connected I have this short crack every 5 to 30 seconds. I tried adjusting all the settings in the bluetooth section but non works. Since it worked in havoc OS I figured it must be something software related. Same with the mic. It works flawlessly on calls but upon sending a whatsapp voice message it's very quiet it sound like it was adjusting the sensitive very quickly up and down during the recording, producing a weird sounding message.
Do you have any suggestions how to fix this? Maybe something inside the build.prop or audio related xml files in system/etc?
