Well, to start, which version of the driver are you running?
(cat /proc./asound/version).
Also, what model Gateway? What is the output from
http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh
These tidbits will help to get your system supported. What Windows does
during use and what Alsa does can be completely different due to
numerous factors. But for the Sigmatel codecs, the key is the
initialization settings for the pins. Once these are set properly, the
sound will work almost the same (well, alsa doesn't have the bloat that
Windows has).
