The first time I open /dev/dsp0, the sb loads automatically, and stays
loaded after /dev/dsp0 is closed (at least, it's listed by lsmod).
Then I try to open /dev/sequencer, but it hangs. This is not new
behavior, but used to I could "modprobe adlib_card", then /dev/sequencer
would start working. Now, it never does open. *Meanwhile*, somehow,
the sb module got unloaded, and won't autoload again. I can do
"modprobe sb", and this gets dev/dsp0 working again.
I may have misconfigured things. I find the isapnp and module stuff
really confusing.
