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

[MAZ]

Hi,

I looked at stdout from mythfrontend and mythbackend.
mythfrontend is now set to "ALSA:default" (Audio-Device) and "default" 
(Mixer). There is still no sound in LiveTV but I can change the Volume 
with F10 and F11 (I can change the volume of the noise). ;)
Mythbackend is set to /dev/dsp as I wrote before. Every attempt to 
change that has failed. I looked at the "-v all" output and when I 
create a new capture device (with audio-device set to ALSA:default) the 
mysql-output shows that it writes /dev/dsp to the database. I tried to 
set "ALSA:default" in the database manually but now mythbackend can't 
initialize the capture device.
What should I write into the audiodevice-field in the database?

Thanks!
Mathias
