tv-card configuration in Suse 9.1

Hi all,

Yesterday I did a clean install of Suse 9.1. My tv-card (Pinnacle PCTV)
did get recognized properly and I could watch television on my pc. The
problem I had was that I didn't have any sound. I tried different sound
settings from the configuration panel in kdetv, but it wouldn't work.

This morning when I turned on my computer I couldn't watch tv anymore.
The appropriate device (bt878) was no longer in the list under "Devices"
in kdetv. I removed the card from the configuration center and added it
again. When I tried to scan for channels I got an error message saying
that /dev/video0 doesn't exist. 

How can I fix it and how do I get sound?

Kind regards,

Bert Meersma
