I'm playing around with audio record on my sparc. I haven't gotten it to
work yet, but here are a few problems I've noticed:
By default it uses /dev/audio0 and /dev/audioctl0. Now, I have /dev/audio
and /dev/audioctl. Audioplay uses them by default.
The man page says that -i means exit if the audio device can't be opened
rather than waiting. However when you run with -i it prints the usage
message with this:
-i header information
So the man page seems to be erroneous.
