cmpci driver (CM8338A card)

[Christophe TROESTLER <debian00@tiscalinet.be>]

Hi all,

I have been switching from 2.2.x kernels to 2.4.19/20 kernels in part
for DRM and support for SIS5513.  However the sound card, an on board
CM8338A based, stopped to work properly with the 2.4.x kernels.  It is
detected by the cmpci driver (here is the startup message

cmpci: version $Revision: 5.64 $ time 20:16:24 Oct  6 2002
PCI: Found IRQ 10 for device 00:0c.0
cmpci: found CM8338A adapter at io 0xde00 irq 10

) but when I try to play a sound, what I hear is a loud noise with the
distorted sound the the back.  I haven't find any solution on the web
for this (only reports of the same problem dating from January).
Anybody has an idea ?

Cheers,
ChriS
