The devaudio Anthony remembers was in the Brazil kernel maintained by
the Mesa group and appears to have come from some Inferno BU kernel.
It supported exactly PCM, μ-law and a-law.
The current Inferno audio(3) claims to support "ulaw, alaw, pcm, pcm16
or adpcm".

While I was at the labs, I'm pretty sure we had a /dev/audio that could
take different audio formats (told the format via /dev/audioctl). I can't
remember where it came from, though. Was something like this ever in
Brazil, or was this specific to our group (Mesa; Geoff?)? I believe it was
limited to things like PCM, μ-law, and friends, at different combinations
of stereo, mono, and bitrates, not anthing as complex as mp3.
Mostly just trying to fill in a memory gap.
