No background music SCUD

When i power on the cab, the attract sound works. When i press start, the music stops. No background on any of the stages. What's usually the cause of no background music? Every other sound works.

Looks like i found my answer, from another forum. i need a bsd1 as the bsd2 board is not compatible w/ SCUD.
