I installed new sound drivers and now I can't control volume!

I’m having a terrible time with my computer lately and it has all been caused by my attempts to get Myst III to run.

I installed Myst III:Exile and in order to get it to run, the people at the tech. support told me to download new sound drivers.

I have Crystal Audio Codec and downloaded the latest driver. Problem is, I can’t control the volume now. It’s up full blast!! When I try to use the volume control thing, it doesn’t do anything! Help!

Gosh, I have had the hardest time. Show some mercy and help me!

one place to fiddle: control panel, multimedia, audio playback, then check the three items there: voloume, preferred device and show volume control on taskbar
