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

[LiM]

Hello,

i have the same problem as http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/11441 also with Hercules Smart TV Stereo ..
works OK audio+video on ..2.6.29-gentoo-r5 + bttv 0.9.17
but NO AUDIO on linux-2.6.31-gentoo-r6 + bttv 0.9.18

I think problem is in new bttv driver, in modules is new options
audiodev and tvaudio is loading with bttv? and this line:
"tvaudio' 6-004b: pic16c54 (PV951) found @ 0x96 (bt878 #0 [sw])"
is only with older bttv.

modinfo -k 2.6.31-gentoo-r6 bttv
---cut--
parm:           autoload:obsolete option, please do not use anymore (int)
parm:           audiodev:specify audio device:

         1 = msp3400
         2 = tda7432
         3 = tvaudio (array of int)
---cut--

How can i load module with new bttv to get sound working?

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?

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.
