Big problem with playing sound after factory reset - LG Optimus L9 P760, P765, P768, P769

Hi,
Few days ago, I have done factory reset(becouse of lot of apps). And then it started. When I play any sound from headphones or built reproductor I can hear it good for few seconds but after a while I cant hear anything. Because of noise. That noise stops after few seconds when i stop playing sound.According to noise in built reproduktor I thing it will be SW problem. I tried more factory resets...but nothing helped.
Edit: I tried to watch something on YT so I have connected my headphones and my phone just restarted after a few seconds watching a video. Sound was turned off and noise was there still.
Sorry for my bad English.

Same on my device. It's a hardware problem because it is reproduced on miui, cm, stock roms with or w/o sound mods... ;(

How to solve it ?? any idea

get in download mode to reflash the rom

The board need to be replaced. Go to the LG service center and ask for help. I have changed it once without telling the unlocked bootloader. They replaced a new locked bootloader board for me. Good luck:good:

So i did. On friday i will have some news about my device. The noise was so loud that it woke up my wife late night

I just got back my device from LG Service. They repaired mainboard (?) and replaced a ribbon(??). and ofc locked my bootloader <), But there is no annoying noise!
There is no noise on headphones/speaker/loudspeaker and no noise on callers device... i guess this was not the first device on LG Service

Most likely , they did not change the board , only fresh the firmware
Lg's service is horrible , they are always lying

Do a recovery update from the lg mobile support tool on your pc. This will wipe everything, but re install the os, potentially fixing the problem.

Now no sound

Another bug i expect
No sound plays, ringtones music nothing, camera says "Camera Failed" on launch and all videos show "cannot play this video"
Rebooted and still the same.
Oh what fun
I have seen the same loss of sound and video stopped playing, but for me rebooting has fixed it (so far )
I also have a suspicion that it's the audio service crashing which might be causing some of my spontaneous reboots...
Roll on the next update from Samsung... hopefully 2.3.4 which fixes some of the battery issues too.
Left it off for an hour and now seems to be ok

Factory reset if problem comes back .

Soundpool error
Just happened again, so I took a look in aLogCat...
Lots of Soundpool (2697) Error creating AudioTrack
My guess is that something is leaking audio streams and this stops any audio playing and the knock on effect is no video either
Not had it happen again (yet) ,
Lost trust in the phone, will it ring? will i miss an important call?, was happy with the G Tab thats the only reason i purchased the SGS2, oh well you live and learn.

I know how frustrating it must be, but it's only one phone out of how many thousands sold?
Just get it exchanged.
Factory reset cures many problems .

Cant do an exchange, only option is to send it away for a month for repair
It happened again, so I checked what happens when I get an incoming call...
No ring tone, only vibrate. When you answer the phone you can't hear the other person and they can't hear you... not great for a phone
It's clearly a bug given that the phone works fine for hours and then the audio service fails.
I run with audio clicks turned on, so it's obvious when it's failed, unlike a friend at work who runs his in silent mode...he also won't know when the phone has done a spontaneous reboot (mine did just now...sitting on the desk with screen off and locked).
Roll on XE3!
Mine done the same last night. I have turned on touch sounds for now. Also get reboots with it just sleeping on the shelf.
Strange as i have two SGSII and the other is fine. Both KE2

Done a factory reset as it was getting annoying. Now it's been 24 hours and i've counted 8 spontaneous reboots all while phone sleeping.

Need help: Xperia Mini sound problems!

When playing any kind of sound (game, music etc.) after some time (sometimes 10 minutes, sometimes an hour, sometimes 1 minute) my phone starts producing crackling noises through the speaker or my headphones. The problem randomly appears and randomly dissapears. It is the same for the loudspeaker, headphones and speaker for calls.
The repair shop said they don't want to repair it, long story, so that's not an option. Any advice on what to do?
EDIT:
Btw, it's not a sofware issue. It's the same on the stock ROM and on custom ROMs.

May I say I'm very, VERY curious about that?
I reverted back to the stock software using a firmware flash file here from the forums. Also relocked the bootloader and unrooted. They still claimed it had modified software and wouldn't repair it.
Anyone?
loudspeaker problem
I also have problem with my xperia mini loudspeaker.
It occasionally not functioning at all. I bought mine last June and it happens twice.
I tried rebooting but nothing happened. Earphones are working fine btw.
It seems to be a hardware problem.. Is your phone still on warranty?

the only way u can see that issue is software related is to install a diff kernel, which in turn will void ur warranty.
hence the ideal thing is to visit a nearest Samsung service center, as ur handset is still under warranty
do not mess around with things, so that later ON u repent with

I have this problem before...
I solve this by plugging in my ear phone then unplug it... simple
Maybe you should try this method before wiping your phone :fingers-crossed:

How 'bout you try using SE update service? Whenever I bricked my phone without a solution, reflashed with seus and everything worked. Of course, I cannot for sure say that it'll work, but give it a try.

Please press thanks if I helped .

Hey man hi , about that i already tried using SE today and nothing changed . Anyway if anyone can respond is there something like driver for sound in these android which comes with software . It seems i will have to take it to the service.
this is funny because i just left my phone today for repair due to the external speaker, i was watching a youtube video and the speaker went crazy and then silent (the battery was very hot as well)... I tryed to flash the original firmware just to make sure it was not a custom rom bug or error but nothing changed...the speaker was dead... So for me the only solution was to take it for repair, lucky for me it was still in warranty. if your's is in warranty as well, better put the original firmware again and take it for repair as well, it will almost for sure be the speaker that died...

Problem with microphone

Dear friends,
I have a problem with mic after 2 months of use. When I answer the call, callers tell me that sound cuts for 5-10 secunds (for each second) and after that, everything is ok.
Factory reset 2x...happens again.
Where I can found original firmware for my phone? Trying for days, unsuccessfully...
P.S. I have expirience with Samsung and Huawei...but this is my first HTC.
Any suggestion?
Thanks!

Thank's for opinion!
I'm not shure it's hardware...
I'll add the fact that after factory reset, 10-15 hours phone is working ok. After that problem starts.
I restart phone for the third time, but without HTC backup from previos session (what I did previous 2 times).
I'm waiting...
I can't figure which, but I'm sure that it's about some application...
