CAUSE

This behavior can occur if RSX 3D Audio is installed on your computer. RSX 3D Audio is installed with some VRML browsers and 3D animation programs.

RESOLUTION

To resolve this issue, configure RSX 3D Audio to work with the Microsoft programs listed earlier in this article. To do this, follow these steps:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


  1. Use Registry Editor to open the following registry key:
          HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Realistic Sound Experience\2.0
    
    					
  2. Modify the value data of the Device Type value to "wave" (without the quotation marks).
  3. Quit Registry Editor, and then restart the computer.
If these steps do not resolve the issue, remove RSX 3D Audio from your computer. To do this, follow these steps:

  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click Add/Remove Programs.
  3. On the Install/Uninstall tab, click Intel RSX 3D, and then click Add/Remove.
  4. When you are prompted to remove Intel RSX 3D, click Yes.
  5. Click OK, and then close Control Panel.
To delete any copies of the Rsx.dll file remaining on your computer, follow these steps:

  1. Click Start, point to Find, and then click Files Or Folders.
  2. In the Named box, type rsx.dll.
  3. Click Find Now.
  4. In the list of found files, right-click the Rsx.dll file, and then click Delete. Repeat this step to delete any other copies of the Rsx.dll file that remain on your computer.

Community Feedback System

Very often, it takes hours to solve a problem. Very often, you've looked high and low, and have tried a lot of solutions. When you finally found it, chances are, it was because someone else helped you. Here's your chance to give back. Use our community feedback tool to let others know what worked for you and what didn't.

Please also understand that the community feedback system is not warranted to be correct, it's simply a system that we've built to let people try and help each other. If something in a feedback response doesn't make sense to you, or you're not comfortable making changes that the feedback talks about (like registry edits), please consult a professional.

Thank you for using kbAlertz.com Feedback System.

We get the MMSYSTEM 320 error because we don't have a sound system. Is that possible?
