Weird problem: Suddenly can't hear anything with VoIP apps!

[Numl0ck]

It's very strange, from one day to the next all my VoIP apps (Nimbuzz, Softphone, Siphon) stopped working properly. I can't hear anyone through the internal speakers but people hear me. When I activate the external speakers, everything's working normally. With the headset there's no problem either, nor is there a mute switch on.

Anyone with an idea what it could be?

sometimes an app doesnt release the volume control.. if i´ve played music with spotify or tunein etc. , when i start a game that normally has music, its totally quiet
doublepress terminate all "music" apps (and the game in question) always solves it... doesnt happen very often thou, and if i just like u change the output from internal to headphones, bluetoooth it seems to resolve itself

Thanks for replying but I really don't know how to solve it. I tried rebooting, bluetooth on/off. The internal speakers don't work with my VoIP apps, only when i make normal calls.

I appreciate every hint, as I need VoIP on regular basis.

I got my earpiece sound back. It seems to be a skype related bug:

After deletng the app and hard rebooting, everything's back to normal.
