Hi mountaineer,
What operating system are you using?
Do you have the speakers plugged into the correct jack? Is it plugged into the SoundBlaster card and not the motherboard sound jacks?
Is the speakers turned on? Is the volume set above the lowest setting?
Is there a speaker icon in the systray (next to the clock)? If there is, double click on it and make sure nothing is muted (that you don't want muted).
As for the extra drive showing up, you could try booting into Safe Mode, go into Device Manager and delete/remove any duplicate entries for the drives.
