Sudden audio problems

[Sam Valiant]

Hey all,

So my S3 is running Cyanogenmod 10.2.0 which is to say Android 4.3.1. It's been completely faultless for over a year and then suddenly today I pick it up off my desk and the audio has gone all weird. Anytime the audio outputs are used the phone makes loud crackly noises, sometimes it makes that noise that phones used to make in the old days when you put it near a hifi/amplified speaker. It makes it if I press volume up, if I use watch something using the youtube, vlc or rocket player. It does when on the startup tone of the phone and also when making calls I can't hear them and they can't hear me.

I've restarted the phone. I tried just yanking the battery out and leaving it out for 45mins without luck. Any ideas?

Cheers muchly!

Hello and welcome to the forums!

Sounds like a hardware problem with the speaker.
What happens if you use a pair of headphones? Do you hear the same scratchy audio? If not, it's time to replace the speaker module (ex. http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-iii-loud-speaker-replacement-service/ or you can find the part online and DIY).

In that case this would be the second time I've replaced that bloody module. Last was because I only had an output on the left side of earphones. Anyways since my post I've reinstalled CM10.2 and when that didn't work I redid the rom and installed CM11 M9 which didn't make any different.

But how comes when I get/make a call, they can't hear me?

Bad things come in threes?

That sounds like a microphone problem. Does it behave any differently if you use the Speakerphone?
What happens if you record a video using the Camera - is the audio present as expected?
Perhaps the mic hole just needs to be cleaned out?

Sadly no audio when recording video

Bummer - time to replace that module.

But the if memory serves the mic and speakers/headphone out aren't the same module. Why would two go at the same time?

 

[GSDer]

Yes, they are separate modules. Just bad luck I guess. Has the phone gotten wet in the past?

Yep about 3 months ago and it was working fine until this weekend just gone.

The long term effects of water, even if you followed the rice drying method, can have a detrimental impact on electronics (corrosion, shorting across contacts, etc) - unless you follow stringent procedures to clean electronics (which 99% of the people are uninformed/unwilling/unable to do) it's a crap shoot as to if/how long the device will continue to function. Sorry.
