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

[MAZ]

Hi!

thanks for your help.

I changed the mythbackend setting back to /dev/dsp but I still have no 
sound in my recordings.

When I use "cat /dev/urandom > /dev/dsp" I can hear sound. But when I 
try "asound -D /dev/dsp track_2.mp3" I get the following message:
"ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM /dev/dsp
aplay: main:542: audio open error: Datei oder Verzeichnis nicht gefunden"

:(

Thanks,
Mathias
