[re: SparcStation audio chip ]
> Any details, comments, references would be great.

The audio feature of the SparcStation has been pretty well described
in comp.sys.sun; inquiring minds who want to know should look there. Briefly,
there is a directory (/usr/demo/sound) that includes a little Sunview program
to display and playback a sample. It comes with a sample of the Sun CEO
blathering about Sun meeting challenges, or something like that. The
chip is a stock 8-bit, 8k samples/sec telephone chip (similar, if not
identical, to the one in the NeXT). It's raison d'etre is voice email. It
is not suitable for reasonable quality audio reproduction. The chip is
accessed via /dev/audio; you can cat a digitized sample to this device and
hear it.  Comp.sys.sun had pin-outs for the non-standard cables you'll need
if you want to record your own samples via the mic input. The program sound.c
in the /usr/demo/sound directory will provide all the gory ioctl details
for anyone who is interested.
