Why not put the whole sound system in userland? It has been done before. Sound
is just not performance critical at all and it's almost never mission

There are dozens of companies selling Linux powered professional audio
gear, multiple pro audio centric distros, and hundreds of serious free
software audio apps. I suspect these developers and their users would
disagree.

I agree with you about userland drivers but at minimum this would
require merging the -rt kernel patches, otherwise the latency/jitter
will be too high to do anything but toy desktop sounds, then you need
a mergeable mechanism for doing DMA and interrupt handling in
userspace. It has been attempted before but never evolved to the
point where you could drive a complex device like the emu10k1.
