I recently got audio with tv card, first must connect a physical wire (red,white,black) from the video tuner card to the mother board or your sound card, then do
Code:
modprobe snd-bt87x load_all=1
sox -t alsa hw:1,1 -t alsa hw:0,0
And you should be able to hear the sound as you change through the channels, (if still not, dont forget to max the pcm volume in your mixer options)
Thanks,
Ted
