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. xof -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
