Hi everybody!

I've never played with tv cards on Linux before, so I'm going to need some guidance

I have the mentioned tv card (antenna/analog) and so far I've installed TvTime from repository. When I run tvtime I can see one national tv channel, without sound though (volume is on maximum), and I'm unable to switch channels with up/down arrows. When I press them, nothing happens.
Output sound from tv card is connected on auxiliary connector on my Audigy Soundblaster2 sound card.

So, what do I have to do to enable the sound and how can I scan for channels?

If you need additional information just ask.

Thank you!
