All of a sudden I have no sound with my HTC One S (running Android 4.1.1). No sound is heard when someone tries to call me, and, curiously, the microphone is also muted; the one who's calling me doesn't hear anything either. I also cannot play audio (it says something like Cannot play this type audio file).
What on earth is going on? And how to solve it?

PS: I have not spilled coffee or something over my phone; no unusual things happend to my phone, as far as I know.

  • Rooted? Recent apps added? Does everything look "normal" under Settings > Sound? – ale Sep 25 '13 at 15:54
  • Maybe some "Silent Mode" or profile enabled? Or (might sound stupid) headphones plugged in? – Izzy Sep 25 '13 at 16:04
  • Have you tried a factory reset? – Liam W Sep 25 '13 at 18:19
  • Everything looks normal under sound settings. Also, the silent profile is not active and there are no headphones plugged in. I have once applied factory defaults. Nothing helped. In addition, the phone has not been rooted. Is it maybe a glitch in the software (either Android or HTC SDK version)? – MC Emperor Sep 26 '13 at 10:17
