I just installed an audiophile 2496 sound card and I played a minidisc through it but I got no sound. So I went to Start > Control Panel > Sounds, Speech, and Audio Devices > Adjust System Volume to check the volume and the "Device Volume" option under the Volume tab is grayed out and it is set all the way on Low so basically it's on mute. since it's grayed out I can't change it so i won't be able to get any sound until i figure this out. anyone know what's going on?
