problem configuring PAS16 and RedHat 5.2 w/ modular sound

Hi.  I hope some of you can help me with this.  I have spent a lot of
time reading the howtos, searching dejanews, doing trial an error to get
as far as I have, but I think that now I need some more help, please,
hopefully from someone who has fixed a similar problem in the past.  I
just joined the list yesterday.  If there is some FAQ I should have read
first, I apologize -- please point me at it.

I'm having problems setting up a Pro Audio Spectrum 16 with RedHat 5.2.
I seem to have it partially set up, because after I use sndconfig to set
up the parameters, the sound sample ("Hello, this is Linux Torvalds, and
I pronounce Linux, 'Linux'") does play correctly, with no error
messages.  I can cat the file to /dev/audio, and it works fine.   But
when I use a program (xaudio, x11amp, tk3play, it doesn't matter which)
to play mp3's, I get extremely scratchy sound, and I get messages
saying, "Sound: DMA (output) timed out - IRQ/DRQ config error?"  I don't
doubt that I have a config error, but I'm having trouble tracking down
the conflict.  Several times, I have gone into DOS (DRDOS, actually --
NO MS on this machine!) and used the install program that came with the
sound card to change the parameters, and then used redhat's sndconfig to
match those parameters.  I have tried a few different available
configurations, but I always get the same thing: very scratchy sound and
that error message.  Here are the IRQ, DMA settings I have tried:
I/O port, IRQ, DMA:
220, 7, 1
220, 3, 3
220, 7, 0
220, 3, 0

I am not enabling the SB compatibility of the sound card, so I guess I'm
attempting to use the card's native capabilities.  Also not enabling the
MPU401.  I'm only using the card for the D-A capability.  I have use the
aumix program to put all other inputs down to 0%, using only the DSP set
at about 70% volume.  The sound sample from sndconfig sounds fine at
that level.  Clear, with not too much background hiss.  When playing an
mp3, the music is clearly audible below the scratchiness -- it's not
distorted.  It's not the same wild distortion that you get when you cat
a .au file into /dev/dsp.

Here is my machine configuration: Dell Omniplex 590.  90 MHz Pentium, 16
Meg ram, two ide hard drives, 3Com etherlink III on IRQ 5 (I still get
the same problem when I remove that card).  Running the stock kernel of
5.2 as it came on my CD from LinuxCentral (2.0.36), which is, if I
recall correctly, actually a pre-release, version 2.0.36-0.7.

Attached is a typescript of some more configuration information, and my
latest /var/log/messages file.

Any help you can provide that would point me in the right direction for
resolving this configuration issue would be greatly appreciated.  I
really want to attach this system to my stereo, convert all my CDs to
mp3, and listen to my music...

Sincerely,
