Thats how it works unfortunately, you can only playback recordings
using the built in decoder , I think you have no choice but to use the
overlay to play back dvd etc, which means that the sound is not output
from the pvr-350. People kludge around that by using sound crd output
and connecting the output from the 350 to line in or running arecord
piped into aplay to record and playback the 350 output.

You could use a usb sound card, I've used a turtle beach audio
advantage micro which is cheap and works ok, and it has spdif output,
but no input.. somebody posted to this list recently with a link to a
very cheap usb sound stick with 3.5 stereo input and output, that
might be a solution but it probably wouldnt have a onboard mixer so
you would have to arecord/aplay and that can introduce delay, although
you can adjust the audio delay in myth to compensate its not ideal and
i found that it was hard to keep sync :(.

Support for the pvr-350 as a output device is unmaintanied and will be
dropped if/when it is broken by some other change, so you might want
to think about driving your tv another way .
