bt878 card: no sound and only xvideo support in 2.6.31 bttv 0.9.18
Hello,

For my Hercules Smart TV card sound also disappeared after 2.6.29 with the message:"bttv0: audio absent, no audio device found!"
I have bisected the problem to commit 859f0277a6c3ba59b0a5a1eb183f8f6ce661a95d:
"bttv: convert to v4l2_subdev since i2c autoprobing will disappear"
If I revert this everything works again

Hi,
and is any chance it will be working with new version?

Hi,

Michal
A temporary solution (if you can use a solder iron) is to get audio out of the (tuner) metal box and inject it at the CD connector on the motherboard.
See : http://www.genicus.be/?p=592
(It works for me. There is an audio out pin (AF) on the TDA9801T in the metal box. lip-sync is not perfect, but, at least, I hear something...)
But, of course, it would be better to make the driver work.
I had the same problem in 2008 when somebody changed tvaudio and I did not realize I had to specify new options in my /etc/modprobe.d/bttv.conf file. I wonder why 'bttv card=100' is not enough to specify the hardware and what to do with it. There is an entry 'Hercules Smart TV Stereo' in bttv-cards.c. I am not sure what can be done with autodetecting chips on an unknown board. I agree, this is probably complex matter but this mix of specification and autodetection is suspect.
My card is 1540:952b - Hercules Smart TV 2 Stereo.
there is a TDA9801T in the metal box labelled TVF-8533-B/DF a Conexant Fusion 878A (~compatible Bt878)
a TDA9874AH on the (audio) piggy back
and two other chips (?pic16c54 (a dip-18 labeled 'B05')? and ? a dip-8 with Label 'GI0')
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.31.y.git;a=commitdiff;h=859f0277a6c3ba59b0a5a1eb183f8f6ce661a95d
is difficult to follow as there are changes in i2c handling, autodetection, v4l and v4l2 architectures,... I don't know if there is some documentation about the (reverse engineered) wiring of the board themselves or is the code 'is/was' the documentation.
The 'Hercules Smart TV' is probably not the only card with a sound problem after those reorganisations. I also hope that it is not a 'big bug' and that it will be back one of these days but (I feel) it is nearly impossible to help from outside.

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.
