Hi all, I don't know if anyone here will know the answer to this, but I thought I would give it a shot. I am running linux 2.6.0-beta9 and the alsa drivers included in it on an old dell desk top that has the CS4610/11 sound chips. Output from lspci for this sound system is as follows: 00:0b.0 Multimedia audio controller: Cirrus Logic CS 4610/11 [CrystalClear SoundFusion Audio Accelerator] (rev 01) When I try to modprobe snd-cs46xx I get the following in dmesg: PCI: Found IRQ 9 for device 0000:00:0b.0 create - never read codec ready from AC'97 it is not probably bug, try to use CS4236 driver Sound Fusion CS46xx: probe of 0000:00:0b.0 failed with error -5 I attempted the cs4236 driver, but got no where there either. Does anyone have any other suggestions to make this sound card work? Your help would be greatly appreciated. William
