I had sent this to freebsd-hackers, but I got no response, so I'm trying freebsd-questions... Basically, it comes down to two things: 1) Just what, exactly, is the Microsoft Sound System and how does it relate to the sb driver. 2) I'm getting: ad1848: Auto calibration timed out(3). and lots of scratchy sound; does anyone have a clue? - Thanks - - Dave R. - > > > OK - > > At Sujal's excellent advice, I've tried another tack on getting > my sound card to work. > > For those who might know what's going on, this is something > called a MediaMagic ISP-16, driven by the OPTi 82C929 "Multimedia > Audio Controller". > > > This is one of those cards that requires an initialization program > be run before anything works (and doesn't save the initialization > anywhere...) i.e. I have to run a DOS program to set the card > in SB-pro mode before booting FreeBSD; then the sb0 driver works > just great!
