SIS7012 works but get's frozen

Hi kernel hackers

I have a sis7012 sound card with my new laptop SonyVaio PCG-GRT100 but the sound is not working. I tried out with the kernel i810_audio modul, with the OpenSounSystem, and with the alsa too, but with every driver my sound card is not working. The modules are loaded, and i can change the volume with aumix, but if i try to play a sound file, just the first second gets played, and then my box gets frozen.

Please help, i really want to hear more then 1 second from a mp3 file :) Thanks a lot
Julius
