I am sorry for the misunderstanding then!  We are trying to record from
a direct external audio line (line 1 of the PVR 150).  The audio is
actually generated by a different PC-based platform, we have no access
to, which generates composite video and cinch audio.  The audio input is
fine on a test TV. We need the encoded a/v MPEG2.

On initial tests everything worked fine, we even captured for a week in
a row and it was ok.  But when we installed this for real use, it seemed
to stop capturing audio after a day or so.  We then switched to another
PVR 150 card in the same PC, which initially also worked fine.  A day
later it was also mute.

We tried the "recommended firmware" from the WIKI (2.0.43), and the one
from the ivtv downloads (must be a beta from 2008-07-01), but it did nto
change anything we could see...  We also cold-booted the PC, which had
no effect.

Right now, we are pretty lost here, as we don't understand, what is
going on.

Thanks, Stephan
