Re: [9fans] audio standards -- too many to choose from

[Anthony Sorace <anothy@gmail.com>]

i think russ has it exactly right: keep the kernel driver as simple as
is practical, do whatever else you want in user space. for /dev/audio,
i wouldn't suggest anything beyond plan 9's audio(3) as is. i'd
suggest some cleanup of the surround (kill /dev/volume, rationalize
/dev/audioctl), but the fundamentals are right.

having a user mode fs on top of that to do easy, standardized format
conversion would be pretty neat, and i wonder if it could be provided
in a backwards-compatible way without too many contortions. if we're
only being additive...

maybe not, though. maybe just keep the names clear and avoid the
compatibility trap all together. i don't exactly follow erik's upas/fs
analogy, but i do think a fs of sorts is very interesting. i think
that approach also lends itself well to mixers, which is a related set
of questions. i tend to think of it more analogous to /net than
upas/fs. "cat whatever > /mnt/mixer/new"?
