"did you try the oss extension instead of alsa - this would probably work better.
what error did you get with cups?"
I did click the "sound on" in the OSS extension, with no results.
As for CUPS, I can't find it. I typed "localhost:631" in the address box, as I've done with other distros, but I can't connect.
It may be that my hardware is too shockingly old for any hope of success. It's an NVidia Riva 128 video card, for example, which never works with any Xorg configuration.
Thanks for your consideration, though.
