hi
just to mention i followed the wiki and the forum posts to setup my audio using the pvr350 tv-out. But for me it's not really clear what to set.

Specs:
Asus Pundit-S, Audio SiS 7012, PVR-350 PAL, Knoppmyth R5C7, pvr350 setup chosen when installed.
Connection with the original cable from S-Video out (PVR350) to Scart (TV) . The Audio cable thingy which is part of the same cable is plugged into the Pundit Soundcard's Line-in. The Soundcards Line-Out goes to my Amplifiers Line-In.
This config represents 10A) in the wiki.
But i am using analogue audio connection (wiki says SPDIF is not possible with SiS 7012)

Alsamixer settings (only unmuted items listed here):
Master 75
PCM 75
CD 75
Line 75

Mythfrontend-Setup (expressions translated from german sorry):
1. Settings--> General --> 3. Page [Audio]
Audio Output=/dev/dsp
Using internal volume [checked]
Mixer=/dev/mixer
Volume Control=Master (see wiki)
Master Volume=75
PCM Volume=75
2. Settings--> TV --> Playback--> 5. Page [Hardware-Decoder]
Use PVR-350 MPEG Decoder [checked]
Video Device of MPEG Decoder=/dev/video16
TV-Audio Out on PVR-350 only [UNchecked]

My problem is:
Watch TV --> Picture and correctly synced audio on TV and TV-Speakers (Scart)
but on same time i have just noise on the amplifier, so no audio through Soundcard.
Logically i can get rid of the noise if a mute line-in in alsamixer, but i would like to use my amplifier.
