Bt87x Audio Capture

["Ondrej Ivanič" <ondrej@kmit.sk>]

Hi

I have problems with audio capture function on my tv card. After 
`modprobe snd_bt87x', I have got nothing in logs (dmesg, messages).

Last relevant info is from bt878 module:

bt878: AUDIO driver version 0.0.0 loaded
bt878: Bt878 AUDIO function found (0).
PCI: Found IRQ 12 for device 0000:00:0a.1

I don't have an idea what is wrong, because I can't found any output 
from snd_bt87x module.

Thanks
