I checked the CD that came with the sound card. There is no DOS software
to be found on it.

I used to try to keep NIC on 9, but these ISA sound cards in OS/2 just
won't work on 5.

I see the numbers, but they really have no meaning to me.

Looks OK to me, but sound has been disabled by removing it from
/etc/modules.conf. Mouse always seemed to work fine before running
sndconfig.

I don't see anything in this output that tells me anything. I'm not a
programmer.

Most times, I ran sndconfig right after booting, let it make its test to
prove sound works, then restarted the whole PC to see if the mouse still
worked, which, of course, it never would.
I have a rather similar system that had RedHat 6.1. Yesterday I
installed Redhat 7.3 on it. The installer ran sndconfig automatically,
and successfully, during the install.
The RH7.3 machine also has Mdk 8.2 on it, but I never yet tried running
sndconfig. During install ISTR that I told the installer that there was
an ISA sound card. It has only one sound card line in /etc/modules.conf:
'alias sound-slot-0 sb'. I took a break here and booted the box to 8.2
to run sndconfig. It found the card, & played the voice sample OK, but
produced errors attempting to play a MIDI sample, and failed to write a
new /etc/modules.conf. I put in the sound lines from the RH7.3 manually.
That produced working CD player and KMedia, but non-working volume
control in KMixer and CD player. I changed to the sound lines from RC3,
but that produced no changes. Back to RC3 sound/psaux diagnosis.
The whole of RH7.3 /etc/modules.conf is:
alias parport_lowlevel parport_pc
alias scsi_hostadapter sym53c8xx
alias eth0 8139too
alias usb-controller usb-uhci
alias sound-slot-0 cs4232

options sound dmabuf=1
alias synth0 opl3
options opl3 io=0x388
options cs4232 isapnp=1
In strong contrast, /etc/modules.conf from RC3 contains:
alias sound-slot-0 cs4232
options sound dmabuf=1
alias synth0 opl3
options opl3 io=0x388
options cs4232 io=0x530 irq=5 dma=0 dma2=0 mpuio=0x330 mpuirq=9

That's all the differences. Same include: ET6100, sym53c875 PCI slot 1,
single IDE HD, CS4235 ISA slot 1, ALN-325 (Realtek 8139) PCI slot 2,
SCSI CD & CD-RW.
I tried changing BIOS settings to stop the usb/eth0 sharing on IRQ 3,
but nothing worked. IRQ 11 stays unused.
Next I tried using the different sound options from from the RH7.3
modules.conf in rc3. That produced another no-mouse result and the
following cat /proc/interrupts:

Since changing from sound resource specifics (RC3) to resource PNP (RH7.3),
didn't improve anything, I switched back to specifics and tried changing
the DMA entries from 0,0 to 1,3 & 0,2, but neither helped. Then I tried
some BIOS changes, as well as moving the video card from slot 3 to slot 4.
Nothing helped until I changed BIOS PCI INT 5 to Legacy ISA, leaving all
others at PCI/ISA PNP. That produced the following cat /proc/interrupts:

This produced working sound, but only briefly. I set KMedia player on a
long MP3, raised the sound level with KMixer, then opened Konqueror. So
far OK. Then I tried to open Mozilla. That produced a hard lockup. After
restart and fscking, I opened Mozilla first, then KMixer, then KMedia. As
soon as I clicked OK on the MP3 file to open, hard lockup.
Next I did more fiddling. I removed the BIOS VGA IRQ, which moved USB
from sharing IRQ 3 with eth0, to all by itself on IRQ 11. I tested
various specifics on the /etc/modules.conf line for the cs4235, eventually
winding up with:
options cs4232 io=0x534 irq=5 dma=1 dma2=3 mpuio=0x330 mpuirq=9
That worked OK for system sounds and playing CD's, but still allowed hard
locks trying to play MP3's off a HD. Smells like a DMA conflict.
Not knowing anything else to try, I created another partition and installed
RedHat 7.3. That gobbled a bunch of time, and produced essentially the
same result, hard lock playing MP3's off the HD, but otherwise OK, using the
following sound configuration:
alias sound-slot-0 cs4232
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 || :

pre-remove sound-slot-2 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
What a nightmare. I guess the sndconfig package in RedHat isn't different
enough to do me any good with this machine. Besides a PCI video card or
forgetting about configuring sound at all, anyone have any ideas to
suggest? Is this possibly a resolvable DMA problem? After all, OS/2 plays
MP3's on this box without locking up.
