The sound on the 600E is weird. It connect to both PCI and ISA for
different functions. As a result, I have to edit /sys/conf/files to
delete the csa pcm entry and add csa to the csapcm line.

dev/sound/pci/csa.c	optional csa pci
#dev/sound/pci/csa.c	optional pcm pci
dev/sound/pci/csamidi.c optional midi csa
dev/sound/pci/csapcm.c	optional csa pcm pci

One line is commented out and the final one is modified.

That's all it took to get sound to work on my 600E.
