Multimedia audio controller: Cirrus Logic CS 4610/11 [CrystalClear SoundFusion
Audio Accelerator] (rev01)

Fresh 2.2r2 installation, just compiled 2.4.3 kernel. When I try to insmod 
cs46xx, I'm receving:
cs46xx.o: init_module: No such device

Same happens when trying to use cs4232 module. Any idea?

Thanks,
Alex
