Acorp Y878

I have a tv tuner which has a BT878 chip paired with a LG tv-tuner. The problem is that i don’t have sound, i have only video. The tv signal is good, image is good. The tuner works corectly on Windows (sound & video). I use TvTime as a tv viewer, the tuner was configured with YAST (card=136 tuner=29). The “audio out” from the tuner is plugged to “line-in” of my sound card (the “line-in” was tested with a mp3-player to be sure that it is not muted). How the sound drivers for BT878 can be loaded? On some forums this problem is related as a bug in 2.6.30 and higher version of linux kernel and/or alsa, can it be fixed?
