(sigh) This appears to be a kernel 2.4.21 problem. Some subgenius working in kernel development broke the sound for this chipset. I had the same problem (indeed, probably the same SiS chipset that you do) and just switched back to 2.4.20.

--It's a real puzzler, because ALSA won't work either. But when using 2.4.20 and earlier, both kernel and ALSA work using the Trident driver.

--Hopefully this will get fixed in the next kernel rev.

But I can't have sound with 3.2 version of 2003/07/26

Here I post dmesg:
