This usually indicates a memory range conflict. 

This can occur in PCs with a SCSI card because of the usage of upper memory.

To correct this: 

  * Go to Control Panel | Multimedia 

  * Select Devices tab (you will get a listing of audio devices installed)

  * Highlight the Pinnacle driver listed under Audio and double-click on it

  * Click the box labeled Settings.  This will bring up a box of 
    configuration settings where IRQ, memory range, and address can be 
    changed.  

  * Select a different memory range.  You may have to experiment with what 
    is the best range to use for your system.  For systems with SCSI, a good
    range to use is d800-dfff.
