Kernel 2.4.6 bug - problems with CM8338A soundchip.

[CuPoTKa]

Part of kernel.log:
kernel: cm: version $Revision: 5.64 $ time 01:44:06 Jul 16 2001
kernel: PCI: Found IRQ 10 for device 00:0f.0
kernel: cm: found CM8338A adapter at io 0xdc00 irq 10

Problem: Sound isn't smooth. It makes strange noise instead music.

I use:
Linux version 2.4.6 (gcc version 2.95.4 20010703 (Debian prerelease)).
Debian testing/unstable linux.
Single PII, 400Mhz CPU.
M748MR PCCHIPS motherboard.

Usefull information: I compiled 2 kernels with CMedia 8338 chip support.
One is kernel 2.4.5 and another 2.4.6. It works with 2.4.5 and dosn't with
2.4.6.

Thanks.
