[mythtv-users] Problems with audio (no sound).

Hi,

I get no sound in mythtv. Both Live TV and recorded files have no sound.
But with xawtv (TV) or VLC (avi) I have sound. I tried to fix that 
problem by myself, but everything I tried didn't solve the problem. I 
tried a few things I found on the web but nothing fixed my no-sound-problem.

I used both alsamixer (console) and the Volumecontrol in Gnome to set up 
the Volume.

After a few changes to my modprobe.conf my /dev/dsp was gone. :)
mythbackend->audio->(none)
Then I but up a new /dev/dsp with "MAKEDEV dsp".
mythbackend->audio->/dev/dsp

Thanks for your help!
