I have been trying to get my snd-cs46xx driver working on IBM T20 with FC4.
Since I am using self-builded xfs dmapi enabled kernel, I was looking into
wrong places. Even when all modules have been loaded successfuly, and programs
were playing sound (they think so), I could not hear anything.
Somewhere on internet I have found reference to PCI power management
in BIOS. After I have disabled it in BIOS, i can hear sound.
Just wanted that others do not spend too much time on this problem,
hope this helps somebody.
