sound suddenly disappeared from some applications


Hi

I am running debian squeeze and KDE 4.4.

3 days ago the sound disappeared on VLC, mozilla flash player (youtube videos and the likes), XINE, MPlayer, Kaffeine, but NOT from Amarok, Skype and Dragon media player...

VLC reports an error about a version issue with ALSA lib, but that seems random, and I guess it would have affected lots of people so there would have been some updates from debian if that was the reason.

I am doing almost daily updates, so it could be that my problem is due to a broken package, but it's been 3 days already, and things haven't gone back to normal, so I think it's something else. I also have a 2 years old at home who loves to play with the mouse and the keyboard so he might have accidentally messed up some configuration...

Any hint? I am not sure what other info I could give. I am not sure what audio system my system is using (how to check?) but I do not have any alsa package installed (i.e. "dpkg -l | grep alsa" returns nothing)

Hi, there is a script for checking your sound system.

It's from the alsa project. This is a plain text file.

http://www.alsa-project.org/alsa-info.sh

The script does not change anything on your system, just reports the output to screen.

Type,
Code:
alsa-info.sh --help
to view your options, like check for update, this is the latest link, send results to pastebin, etcetera.

Please share the output here.

Regards Glenn

Thank you. I placed the output here:

PS: that's a great script. I've always sucked at writing shell scripts. I just found a great example to study.

Thanks. With that info, I managed to solve the problem by compiling the proper kernel modules:
Code:
m-a a-i alsa
I'll file a bug with debian for that. Apparently they are having a version issue
