[Android Q&A, Help & Troubleshooting] /dev/error:
Hey together. I'm a noob *duck* - but I did quite some search on google and on these forums before posting, and I'm not a very stupid noob.

Today I got the situation that no audio is audible any longer from my browser, games, audio apps, or from an audio player (all of them previously worked). This is the case for headphone and also the built in speaker. The problem occurred very likely after using skype. I also still have audio in phone calls and also I still have sound for ringtones and other alarms. Handset functioms all still work fine.

The first obvious thing I did was checking volume settings in the android settings. There I moved all sliders - the one responsible for regular audio did not give me any feedback. If I use the volume buttons on the phone while I'm on my home screen I get audible feedback - but that doesn't influence my problem.

Funnily the sound in skype still works. More funnily: during skype calls the audio from my browser or the audio player is also audible (I tried this just out of couriousity as I suspected Skype to be the cause of my problem. Et voila - I got sound from a TV News page and also from the Walkman app while the call on skype was still running. As soon as the call in Skype ended the audio from browser and adio player got muted again.

I also tried to kill skype during a call in order to kill it before it can again mute the audio - No luck. as soon as the skype app is killed also the audio from audio player and Browser vanishes.

I also tried some audio apps - all have the same issue of having no sound.

I then tried different apps which control volumes - without any luck. So at the moment I don't have audio, except during skype calls.

I guess that skype has either access to some hardware settings which aren't used usually (I hated skype for things like this as long as it had existed) - or I'm missing something very obvious. Or something else. Does anybody of the developers here know about linux settings I could modify? (is there something like alsamixer which is only possible to access via jni or similar?)

// Edit:

Just found out that toggling airplane mode ON I have sound for media (audio player, browser). (but also lose the ability to use my cellphone and network). As soon as I switch back to airplainmode OFF also audio is muted again. And for sure - I also tried rebooting in different states of my phone quite often without any difference.

// Edit 2:

looks like I found a workaround but no permanent solution - I installed an app SoundAbout (free app) recommended for similar problems in an other thread: 89996-galaxy-s3-media-volume-stuck-mute.html (I have now put output permanently to "headphones" for media sounds. However as soon as this setting is reset to the default (let app decide) it is muted again when airplane mod is set to off - looks like an other app resets it? (could not find any app obviously doing this though as I stopped the usual suspects)

I still suspect Skype as the original reason for this problem as I just recently had it updated when the problem appeard and it also messes with this kind of stuff during usage (and I don't really use other apps dealing with audio except of browser, music player which weren't updated for a long time).

Maybe also of concern:

It's an sony xperia p, running Android 4.0.3 and it is currently rooted.
