Then do *not* check the setting "TV audio through PVR-350 only" ("TV-Ton
nur über PVR-350").

The setting "Use the PVR-350's TV out / MPEG decoder" ("Nutze den
PVR-350 MPEG Dekoder (TV Ausgang)") does not affect Myth's ability to
control audio volume. However, Myth can /only/ control the volume of
the Master or PCM channel of your sound card. Therefore, you must
configure your Myth box so that the PVR-350 outputs audio to your sound
card, which your sound card samples ("captures") and outputs to your
speakers/receivers. Since Myth can control the volume of the Master/PCM
on your sound card and since your sound card is capturing and then
outputting the audio from the PVR-350, you can control your volume (via
the sound card) even though you're using the PVR-350.
If you check the setting "TV audio through PVR-350 only", you're telling
Myth not to even attempt to control the volume. Therefore, you do not
want this setting checked.

Note that there are 2 settings related to PVR-350. Make sure you
uncheck the audio one and check the decoder one...
