The patch works as expected.  Thank you!

BTW, I also found the following change necessary in my environment.
Without it I can not record from full-duplex devices, only play through them.

The problem seems to be that FreeBSD doesn't support the following usage pattern:
open(/dev/dsp, O_RDWR);
mmap(fd, PROT_READ);
mmap(fd, PROT_WRITE);

FreeBSD will only support writing in this case.
FreeBSD requires two separate file descriptors to be opened:
open(/dev/dsp, O_RDONLY);
open(/dev/dsp, O_WRONLY);
mmap(fd1, PROT_READ);
mmap(fd2, PROT_WRITE);

But implementing this approach would be a bigger change to the code.
So it's easier to just disable mmap on FreeBSD.

Last note.  Each time I log into a KDE session I get the following message:
pulseaudio[NNNN]: pid.c: Daemon already running.
Looks like possibly some (minor) issue in automatic pulseaudio daemon startup?

Thank you again!
