I downloaded a program called "Anvil Studio" so I could edit some midi files. I played a midi in it, and strangely, I did not hear any sound. Then I tried playing the fixed song in windows media player, and still did not hear any sound. Then I tried playing a song I hadn't touched with the program. I eventually figured out that I can no longer hear MIDI at all. Please help!
I'm using a Turtle Beach Santa Cruz card. All other sound is fine.
