[mythtv-users] Strange sound problem...

[Steffen Schlink]

I have a strange sound problem...

First some details:
iP4 2.6GHz on a i865 mainboard, 512Megs, a few Gigs of harddiskspace, 
Soundblaster Audigy 2, a WinTV 350 PVR and a cheap GeForce card.

This baby runs Slackware current with a custom kernel and ALSA installed 
  from sources. ivtv 0.1.9 works too, a cat /dev/video > somefile.mpg 
gives me a MPEG video with sound, that plays smoothly everywhere.
Mythtv was completly installed from scratch with native support for ALSA 
and LIRC.

I'm using mythtv for about a week, nearly everything works like charm,
except one thing: if I'm trying to view LiveTV or a recorded TVshow I 
can't get any sound out of my box. Video plays smooth. But Mythmusic 
gives me sound without any changes...
Watching a recorded TVshow using mythvideo (mplayer) gives me video 
_and_ sound.

I found mplayer uses an ALSA device for sound, I tried to set 
AudioOutputdevice in mythtv manual to ALSA:<someoutputdevice> (I tried 
more than one!) in the database and restarted mythbackend/frontend, but 
still no luck.

mythtv uses the ALSA device (at least it says it does, there is no 
errormessage) but I can't get sound (a simple ~$ aplay foo.wav works). 
Same with a /dev/dsp setting for AudioOutputdevice - no sound with tv 
related stuff.

In short: sound works everywhere (music, video) except in the tv module!

Someone any ideas?
