PS1 Multitrack Games on PS3

[Pikmin]

I've only recently soft-modded my PS3, still have some reading to do on how to dump discs but I thought I'd ask a question relating to playing PS1 CDDA games using multiman.

I tried Buster Bros and the game runs but CDDA music is missing, sound effects are playing. This was a redump backup with multiple tracks.
I've tried converting it to a single bin using imgBurn but that yielded the same results.

Any tips, if this is an allowed discussion?
