Greg, Check out PlanetCCRMA for getting RH 8.0 updated on a laptop. Fernando has a specialized kernel I believe. http://www-ccrma.stanford.edu/planetccrma/software/ Cheers, Mark > -----Original Message----- > From: linux-audio-user-admin@xxxxxxxxxxxxxxxxxx > [mailto:linux-audio-user-admin@xxxxxxxxxxxxxxxxxx]On Behalf Of Greg > Reddin > Sent: Monday, March 31, 2003 10:41 AM > To: linux-audio-user@xxxxxxxxxxxxxxxxxx > Subject: [linux-audio-user] ALSA 0.9.1 on IBM ThinkPad T20 > > > Hey all, > > I'm sort of a Linux newbie.
