Description of problem:
On my redhat9-system, redhat-config-soundcard will detect my soundcard. It is
well configured and ready to use. No errors, no warnings....but the sound just
wont work!!
The modules cmpci and soundcore are correctly working, loading them manually
with modprobe does not give any error.
The driver is the one provided by CMedia.... 
when trying to play a file with the command play, you will have to stop it with
ctrl-c or it will stay forever without bringing a sound or giving any output.
Also having modules ac97.o or ac97_codec loaded or unloaded the results will be
the same. This "conflict" causes sometimes the system to hang.

Version-Release number of selected component (if applicable):
no sound for cm8738 soundcard

How reproducible:
Sometimes

Steps to Reproduce:
1.Always- you will never get any sound :(
2.This one is courious.My system reezes when trying to play a sound(for example
with 'play'), but only if my system just booted(if its the first  command i type)

    

Expected Results:  I should have sound

Additional info:

cat /proc/pci gives this output(i'll post only the part concerning the soundcard):

Bus 1, device 10, function 0:
Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 16).
IRQ 5.
Master Capable. Latency=32. Min Gnt=2.Max Lat=24.
I/O at 0xc800 [0xc8ff].

lspci -v gives a very similar output with of course the same values.

/etc/modules.conf looks like this:

alias sound-slot-0 cmpci
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1
|| :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

Commenting out the last 2 lines with aumix-minimal does not solve the problem

dmesg | grep cmpci gives the following:

cmpci: version $Revision: 5.64 $ time 18:40:44 May 8 2003
cmpci: found CM8738 adapter at io 0xc800 irq 5
cmpci: chip version = 037
cmpci: Enable SPDIF loop

I should mention that using the latest kernel provided in rpm by redhat or
compiling a new one (2.4.20) does not solve the problem :'(
