Hi,
I've the TV card which is=A0Kworld KW-TV878RF and tv module bttv gives
the vision well.
It registers also the sound device in lspci -vv:

then I load the module snd-bt87x with no argument, then it says the
card is not detected.
Then I load the module as "modprobe snd-bt87x load_all=3D1
digital_rate=3D44100" (also 32k is not giving sound)

Can you somehow help me ? Now I'm going to connect audio-out with
soundblaster line-in, as workaround.
BR,
