Hi,
I'm trying to finish installing an old STB TV PCI FM
6000704 tv capture card working and there's no sound.
I'm on Debian Lenny/Testing kernel version 2.6.24.
The card itself does not detect or load snd-bt87x on
its own and I force it to load with the load_all
kernel option when I modprobe. It doesn't seem to use
msp3400 in any way. In theory,
/proc/asound/card1/pcm0c is the stereo capture, but I
can't seem to get amixer to recognize it. I can set
the digital_rate as needed if that will get stereo
going.
Any advice, or perhaps an .asoundrc would be great.
Best regards,
Michael
