Sound disappears when changing TV-channel

[gridsystems]

Hi,
I just built a new computer and everything works smooth and fine apart from MC. I have Asus My Cinema P7131 TVtuner PCI-card and have use it without problems before on Win7 Ultimate with the native windows drivers (this card is supported directly by wiondows and does not need drivers like XP did.).

Now when I put it inside my new computer I have problems with the sound.

When starting MC and beginning to watch TV, there is sound. But when I change the channel the TV sound disappears, but media center clicks and sounds can still be heard.

What could this behaviour be due to?
How can I troubleshoot it?

Thanks a lot!

I have the exact same problem.

Asus ENGTX460

P7131 looses audio when changing channels. I have to reboot to get it back and it's OK as long as I don't change the channel.
