Have you by any chance tried my es137x patch?  I doubt it would fix your
problem, but as you're using the es137x driver I thought I'd see if it
works for you:
http://www.noacks.org/freebsd/es137x.diff

The patch includes 2 main features (and is a superset of the 2 PRs
mentioned):
1) Adds locking to the driver to make it MPSAFE.  Reducing Giant
contention can't hurt...  This is based on Mathew Kanner's patch in
kern/59349 (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/59349),
although I cleaned it up and added a snd_mtxfree (mutex_destroy) to
complete the locking.
2) Adds digital (S/PDIF) output.  This is enabled via the
hw.snd.pcmX.spdif_enabled sysctl.  Make sure to read the notes in
kern/68594 (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/68594).

I've been using the S/PDIF output since February and the locking since
August.  I've had no problems with either.  However, I am not aware of
anyone other than myself looking at this code, so I'm sure I screwed up
somewhere... ;-)
