Summary:                    Choppy/skippy sound on onboard SiS SI7012-controller
Description: 
The sound on my specific sound controller is very bad. The times it even
plays, the quality is very choppy and it skips almost like a scratched CD,
which makes it pretty much unusable.

I suspect this might be specific for my model laptop as I'm having a hard
time finding anyone else with the same problem, but I've tried several
distros and kernel versions, and the card works in Windows.

The laptop is an Elite Group G732, which has a SiS mainboard chipset with
the SI7012 onboard controller (Realtek ALC202 chip).

I've tried messing with the buffer_size and period_size in asound.conf,
which seem to have some impact on the "pattern" of the chopping and
skipping, but there are no values that I've found that will get rid of
them entirely.

I'm assuming this is an incompatibility with the driver and this specific
hardware, but I could obviously be wrong.

I've tried using the version of ALSA in the 2.6.10, 2.6.12 and 2.6.16.2
kernels, as well as compiled the latest stable and developement releases
of ALSA myself. The result is the same for them all.
