The PVR-350 will only output sound from MPEG files that it is playing, so
there is no way that you can have the system sounds be piped out through
the PVR-350.

What you'll probably need is a special cable (I don't know if one exists
or not) that will let you connect a graphics input and a separate audio
output, and have them sent to a SCART output for your TV.  - a SCART
combiner cable of sorts.  If it doesn't exist, it should be fairly easily
to make one, if you have the skills.

I've always hated SCART since I was introduced to it, and this kind of
situation doesn't make it like it any more.  Wish I could help more,
perhaps somebody who uses SCART (I'm in North America) has more
