Awsome!  This patch fixed the problem for me.

Even after this patch, I was still getting it to "Aborted" occationally, 
but a "make distclean;make;make install" seems to have fixed that.

Thank you!

John

P.S.  What are you using for a soundcard?  I am using an old SB Live!  I 
tried using the onboard S/PDIF, but it caused an occational crackel in 
the sound.
