Description Marcus Köller 2006-03-27 04:21:42 EST
Description of problem:
The sound on my system is muted.
I'm using an IBM Thinkpad R50.
I read in many newsgroups, thath I have to mute some settings like microphone,
line in jack and other things in alsamixer to get the sound working. But this
didn't help the sound is still muted.
If i play files in xmms or other apps the visualization show that the file is
played but i can't hear anything. 
And i really tried a lot of settings in alsamixer/kmixer...

Here are some stats of my system:

--------- Problem Solved ----------
The IBM Thinkpad has 3 sound buttons located top of the keyboard.
One of these Buttons 'mutes' the sound and it was activated.
I didn't think these buttons would work under redhat.
Probably they control the soundcard directly.
bye bye
