sound fails after suspend 2.3.99-pre1

Playing a sound works fine just after I re-boot with kernel 2.3.99-pre1, but after a suspend-resume I don't have any sound anymore.

The only lines I found in the logs related to sound are:

Mar 17 22:17:08 krypton kernel: ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996 
Mar 17 22:17:08 krypton kernel: Found OPL3-SA3 (YMF715) 
Mar 17 22:17:08 krypton kernel: <MS Sound System (CS4231)> at 0x534 irq 5 dma 1,0 
Mar 17 22:17:08 krypton kernel: <MPU-401 0.0  Midi interface #1> at 0x330 irq 5 dma 1,0 

gom still shows the mixer controls, but tweaking them produces no changes.

Thanks,
