I agree, auto detection for sound seems not to work too well for BT878 cards.
To get sound I have to set modprobe options:
options tda9887 qss=0
options tuner pal=i
although the card is auto detected:
bttv0: detected: Pinnacle PCTV [card=39], PCI subsystem ID is 11bd:0012
bttv0: using: Pinnacle PCTV Studio/Rave [card=39,autodetected]
Would be great if there was a method to fix this.
