Thanks for the reply Lowell (or is it Gilbert). Do you know of any additional information on "devfs" apart from the man pages, since I browsed the man page and it didn't make all that much sense for a new FreeBSD user. If all else fails I'll fold back to an earlier release.

This is one of the places where you suffer from running an "early adopters" release rather than one intended for production use -- the documentation for handling sound doesn't cover 5.x nearly as well as 4.x. Read the manual for devfs and whatever related bits you can find. [Sorry I can't be more explicit, but I don't run 5.x yet myself, and I have limited documentation access from the screen I'm currently working on.] The trick will definitely be how to get devfs to create the nodes, because the kernel sure seems to be recognizing the sound chip. Also note that your sound sound subsystem might be getting recognized as device 1 rather than device 0, so in looking for the device nodes, do an (e.g.) "ls /dev/dsp*". Good luck.
