[mythtv-users] Onboard 5.1 Via823x sound card and mythtv?

Hello again,

I've bought a new PC with a 5.1 onboard sound card. I have now no idea how to make mythtv work with it. There are millions of possibilities to change stuff in alsamixer. I just want to have the old behaviour with the 3 jacks as: line-out, line-in (for the analogue tv card input) and and microphone output. 

I'm playing with alsamixer for days now. XMMS/Mplayer both work great but the tv sound is the problem. Sometimes I get sound from xawtv/kdetv when i change volume on Mic1 (!!!) in alsamixer, most the time I even don't get any sound from my tv card. Now I know it's not allowed to turn the volume above 73% in alsamixer but what else do I have to change in alsamixer and in mythtv to get the right sound from this sound card?

I don't want to send my whole asound.state file so i put it on my web space: 

Is there something wrong with my configuration?

My components:
Motherboard: Fujitsu Siemens D1607
Soundchip: via8233 
Debian unstable with mythtv 0.15.1 from Matt Zimmerman.
Alsa 1.0.5
