You can install one of the packages/ports from /usr/ports/audio to 
manipulate sound files.  I use auedit, and friends from the nas port.

I had this problem with an 8-bit sound blaster.  Turned out that the
driver wasn't getting the interrupt from the card.  Double check where
your interrupts are.  Irq 7 is typically used for the printer too. Even with
your printer in polled mode, I'd probably try moving the soundblaster
to another irq.

Actually (from LINT):

...
# wt: Wangtek and Archive QIC-02/QIC-36 tape drives
...
device          wt0     at isa? port 0x300 bio irq 5 drq 1 vector wtintr
...

Yes, if you don't have one of these tape drives, or you don't want
to use it.
