Hi, I could not find related information but the issue I have been experiencing is annoying. I plugged my 920 to car through aux cable. At the beginning the playback was ok until something interrupt the playback such as a notification sound then it started popup noise. Also When I listened music through earphone it was stereo sound at the beginning then it only had mono output when again something interrupt the sound. I have to reset the phone then it was normal again.

Is there some setting could prevent this or this sounds like a bug.

Thanks for your infor
