OK, I understood. I did the following: I checked the option "Use the
PVR-350's TV out / MPEG decoder" and unchecked "TV audio through PVR-350
only" I looped the audio-out-cabel of my PVR350 into the line-in of my
soundcard. I now have the TV sound on my speaker but I can't control volume
via myth. I do not see even the OSD, which indicates the volume. Using an
external mixer like kmix I can change the volume with master and the line-in
controller. That is what I expected. I have set the myth's internal mixer to
change the master volume. Using mythMusic there is no problem, there I can
change the volume.

Strange to me is the following: I do not change anything, I only uncheck
"Use the PVR-350's TV out / MPEG decoder" (which hides the audio option).
Now I can control the volume via myth. But this is not what I want. I want
to use the decoder.

Thanks
