If this happens repeatedly, run Diagnostics ("MSNDDIAG") from DOS.  

Before running diagnostics, you must set the software parameters of the board. 
If you are still at the default settings of Port=290, IRQ=10, and RAMAddr=D000, 
then you are fine.  If not, you will need to use "MSNDSUP" to change the 
parameter settings for the Tahiti/Monterey. 

  MSNDSUP DSPI/O=xx     *Changes the Port Address
  MSNDSUP DSPIRQ=xx     *Changes the Interrupt
  MSNDSUP DSPSEG=xxxx   *Changes the RAM Address

Make any necessary adjustments and then type "MSNDDIAG" to run diagnostics.

A lockup could also be caused by having the Quad drivers installed instead of 
the sound card drivers. To rectify this situation:

  1. Make a backup copy of your "SYSTEM.INI" file. 

  2. Find the [drivers] section of your "SYSTEM.INI" file and check the 
     settings for WAVE=, MIDI=, and AUX=. 

  3. If they are "TAHITIQ.DRV", change them to "TAHITI.DRV" (or "MSNDQ.DRV"
     to "MULTISND.DRV" for the Multisound.) 

  4. Save the "SYSTEM.INI" file and re-launch Windows. 

  5. Run the diagnostics.
