Ok. To start with, audio(3) seems to support soundblaster-16-compatibles.
What about others? I guess mine could be AC'97 on one of my notebooks
(there fortunately seems to be some support for this one elsewhere,
too), while god knows what on another. Connected to this:
How do I find from within plan 9 what soundcard/hardware I have?

Ok. I ask because some widget sets already have an analog-like gauge
I'd like to use, e.g. Tk::gauge. (What'd be the situation in Inferno?
They have some Tk, don't they?)

Thanks
