Audio stutter w/ Turtle Beach Montego DDL, MSI 7098 MB

Hello,
I've been plagued with a sound stuttering issue when playing audio
tracks on
my pc. Here's my setup:
emachines T6212 (msi 7093 motherboard)
Athlon 64 3200+
2 Seagate PATA 160GB drives on IDE1
1.5 G Ram
Gigabyte ATI X800 PCI Express
Turtle Beach Montego DDL on pci slot 3
Interlink Versapoint wireless usb mouse/keyboard
Super-Flower 450W Power Supply
Panasonic PT50LC13 hooked up via VGA.
Whenever I play audio tracks and quicktime movies, I get horrible
audio stuttering/dropouts. The weird thing is that If I keep my mouse
moving, the problem does not occur. This is probably why I don't see
the
problem when playing games (I can play half-life 2 and Far Cry no
problem,
and I've never had video stuttering issues).
I've noticed after adding upgrading the power supply and adding the
second 160G drive,
then doing XP reinstall and updating all drivers, BIOS, etc.
I'm guessing this is some type of USB/PCI card resource issue, but the
obvious things haven't worked for me (please read on)
I've done my homework and tried the following:
-Updated to latest video, motherboard, sound card drivers
-Updated to latest bios
-Tried using different audio players. Same problem occurs with
Quicktime,
Rhapsody and Windows Media Player.
-Disabled all unused motherboard periperals (video, sound, parallel
port, etc.)
-Switched PCI slots for sound card
-Played with changing PCI latency of sound card up and down (via
powerstrip) from default of 64
-Tried IRQ/Device conflict resolution: My sound card shares
IRQ 21 with onboard firewire and ACPI:
IRQ 21 Microsoft ACPI-Compliant System
IRQ 21 Turtle Beach Montego DDL
IRQ 21 VIA OHCI Compliant IEEE 1394 Host Controller
Disabling Firewire controller in windows or BIOS does not
fix the problem. XP and my motherboard bios do not allow for manual IRQ
assignment with ACPI enabled.
As a last resort I have gone through the process
of a fresh XP install with ACPI/IRQ steering disabled (Standard PC),
but I've had
other severe performance issues and lockups in this mode which I was
unable to
fix with manual IRQ assignment.
The fact that moving the mouse stops the audio stuttering makes me
think
that there is something else going on here, and I'm looking for other
ideas
to try. This doesn't make sense to me because the usb controllers do
not
share IRQ's with the sound card (as far as XP reports). I've tried
removing my
wireless mouse/keyboard and using wired ones (in every combination of
usb ports) to elimiinate the possibility that it's the mouse itself
causing the
problem. I also turned off any power saving options on the usb devices.
I guess the worst cases would be that this is a fundamental issue with
the MSI 7093 motherboard or with the Turtle Beach Montego DDL. Another
possibility is that I just need to keep banging at the non-ACPI install
until
I get everything working right, but I've already spent many hours on
this
without much luck. Maybe someone has some tips in this area?
Any ideas would be appreciated.
Thanks,
Colin
