You might want to right click on the sound image on the bottom right of your desktop and click on Sounds. Click on the playback tab and then mess around with the properties. Idk if that will work but again, if that doesn't work, I suggest updating your Sound Drivers:
Steps to identify your sound card and driver version:
- Click on the Start button and select Run. (For Vista Users, press the Windows Key (the key with the Windows logo on your keyboard) + R (at the same time) and skip to step 3)
- Type in dxdiag and click OK.
- After the DirectX Diagnostic Tool loads, click on the Sound tab.
- The version of the driver you have installed should be listed under the Driver box next to the word Version.
