Error 0xC00D11BA: Cannot play the file in WM9 after Santa Cruz card install

I installed a Turtle Beach Santa Cruz Soundcard and its drivers which are
current thru April 2002. The install shows no errors in Windows XP and other
programs such as Real One MP3s fine. However WM9 gives the following error
when playing a file:

"0xC00D11BA: Cannot play the file Windows Media Player cannot play the file
because there is a problem with your sound device, such as a sound card or
sound controller. You may encounter this error message for one of the
following reasons: Your sound device is in use by another program. Quit
other programs that may be using your sound device, and then try to play the
file again. .............................."

During a broken install of the TB driver, WM9 did play the files (the card
and some part of the driver shoehorned into the OS), so it is driver
related.

Are there any workarounds? My research found the following help, but it
contained only registry files w/out saying what was being changed in the
registry:
I'm having sound problems (muffledness, echoes, errors, speed issues,
etc).

A: Check for sound card driver updates, both from your vendor and from
Windows Update (also make sure you have the latest DirectX there). If that
doesn't help, go to "Control Panel"--"Multimedia"--"Audio"--Advanced
Properties" (this is the "Sound and Multimedia" control panel on Win2k) and
turn down Hardware Acceleration. If you're still having issues, you can
switch to use WaveOut for audio rendering which may fix the issue for you
(*Please note that you may need to reboot for this fix to take effect!*). If
it doesn't you must run this to switch back to using DirectSound. Also, this
page contains some good generic audio trouble-shooting info. [NOTE: In all
cases, we're just working around bugs in your audio card driver. WMP uses a
more advanced API than most other players use, which is why often WMP will
be the only player to suffer from the sound card bugginess.]
