I would think its a driver problem, are you installing the correct drivers?

Check to make sure the connection cables are in the right holes.

Did you check creative audio consol settings?

I have formated the computer and did a fresh install of drivers?

You may want to contact Creative support they are very helpful. I had twice problem with MP3 player (I know not sound card) and they been fast to locate what was wrong with it

Please help. I am having the same problem with a Creative SB Audigy 2 ZS card in a Dell Dimension with Windows Media Center.

Sound was working fine and then my cd & dvd drives went down. When Dell was attempting the fix the drives they messed up my sound. I found the fix for the cd/dvd online but no luck getting the sound back so far.

When I have the volume turned up to full, I hear faint, fuzzy sound. When I open the Creative Speaker settings and check or uncheck DIGITAL Output Only I hear a loud pop but nothing else works.

Prior to calling Dell I went thru all of the Creative Diagnostics and MS troubleshooting steps. I have installed the newest driver, rolled back when it didn't work, then reinstalled again.

Dell support has been useless. After they suggested a few fixes that did not work, my Creative Diagnostic attempts now receive an error message and close when I attempt the test.

Any help would be greatly appreciated.

Thank You,
