Your problem is caused by a OpenBSD kernel bug. The kernel does not handle
odd DMA counts for ATA correctly.
But could you try to answer my question please:
If you install cdda2wav suid root and call it as non root user, does it work?
In order to avoid the Kernel bug from preventing you to do the test, check the
number of traks on the CD. It it was a CD with an even number of tracks, use
one with an odd number of tracks or vice versa.
