So about a week ago, I opened itunes on my mac to listen to some music as I normally would through my tascam fw-1184 board. When I hit play, nothing happened, and the cursor just stayed there. I restarted the computer and things went back to normal. Now, when I press play the same thing happens as before, but restarting does not solve the problem. If I unplug the board, the music plays through my powerbooks speakers fine. I have reinstalled the driver software for the board to no avail. Any ideas? (keep in mind NO sounds play through it) When I attempt to playt hefiles through the mix board a very faint high pitched sound comes out of my powerbook in from the left side of the case.
