If alsamixer tells so, it must be in fact ALC650. ALC20x and ALC650 have different codec ids, which is probed via an AC97 register. Anyway, these chips are almost compatible.

It could be a bug of the driver itself, of course, although 8233 seems working fine. According to VIA tech, 8235 is compatible with 8233, so theoretically it should work. Also, please check whether the count in /proc/interrupts increases during playback. If not, it's usually a hardware configuration problem. if it increases, most likely a driver bug. ciao, Takashi ------------------------------------------------------- This sf.net emial is sponsored by: Influence the future of Java(TM) technology.
