low audio volume

[Claude Jones]

I have a fresh install of FC3 on a 1.5 Ghz desktop. All is generally 
well, but, my audio volume is extremely low. Even with amplified 
speakers turned up all the way, and the volume control on my media 
player turned up all the way, the sound is fairly soft. It can be heard, 
but it can't be made loud. Is there a setting somewhere that I'm 
missing? The sound card is built in to the MB which is an MSI, I 
believe. All works well in Windows, so I don't think it's a hardware 
problem.
