I have a bt848-generic-unknown card which I have managed to get working. It tunes all the stations I need and picture is crystal. I can't manage to get any sound though. I have a RH7.1, vanilla 2.4.18 kernel, cs4232 soundcard. I can play sounds okay elsewhere ie(wav) the volumes are not muted. The tv card output is in the speaker line in. The system works fine in Windows. if I turn the speakers waaay up I can faintly hear the sound. But like I said all the mixer volumes are nowhere near zero.. My modules.conf is: (abridged) # i2c alias char-major-89 i2c-dev options i2c-core i2c_debug=1 options i2c-algo-bit bit_test=1 # bttv alias char-major-81 videodev alias char-major-81-0 bttv options bttv card=0 bttv_verbose=1 options tuner type=0 debug=1 Any help anyone??
