The line: "device pcm"
needs to be added to a new kernel configuration file. The easiest way to do
this is to copy /usr/src/sys/i386/conf/GENERIC to a new file. Follow
directions at:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
I think the "pcm0" line is for ISA sound cards.
