Very strange sound problems.

[Stylus]

OS: XP
Soundcard: SB Audigy

My computer started acting strange all of a sudden and I'm hoping someone here can help. I noticed one day that the PC's System Sound didn't work when I signed on. I didn't think anything of it when I clicked on an MP3 to see if everything was fine and the MP3 played no problem. When to browse the internet to check my favorite online comic (homestarrunner.com of course) and I wasn't getting any sound.
I checked the device manager and there weren't any conflicts. I then checked the Sounds section in the Control Panel and noticed that when I went to test a scheme the play button was grey and I didn't have the option to play it. I've updated my drivers I don't have onboard sound so there wasn't anything to disable. Is this some kind of Codecs issue or something? I'm kinda lost. Anyone have a clue?

This tweak is for all the people using a Soundblaster Live soundcard with Windows XP and the latest drivers from Creative. Somehow you are not able to run the program called Speakers located in the AudioHQ menu, but this will fix it.

1) locate the file called ctsurmix.exe in your creative soundblaster folder.

2) Right click it and select properties and then compatibility.

3) Select win2000 compatible mode and it should work again.
