OT: AN35N Ultra Internal Speaker help

I recently installed a 1989 DOS baseball game that I love. It plays great, but there's no sound. I tested it on my mom's IBM and I discovered that the sound from the game wasn't coming from the speakers, but from inside the tower.

Did I miss something in the connection process when I install this mobo? Or is there a BIOS setting I could change to get this going? Thanks.

Did you attach the small internal case speaker to the MoBo header when you assembled it? Page 32 in the manual.
