Glad to hear that. Now the problem is, the chipset seems *broken*
during mixer initialization through ac97 interface programming,
perhaps because how the driver was written, hence require some sort of
wacky monkey circus hack. I don't think it's worth commiting this ugly
workaround, unless we can come up with cleaner approach (complete
rewrite, or some sort of *patching* interface).
