there is always some noise on microphone.
you can open a a stream and if it succeeds run it for a half second
and see how high of an amplitude you get. not 100% reliable, but very
close I would expect. Or perhaps just a table of known devices with
mics? (TX, LD, etc...)

I've tried using SndStreamCreate with sndInput parameter
but the call seems to succeed even on devices that don't
have recording capability.

We have had some problems using input sound streams on devices without
this capability.
On the Tungsten E2 we found that we could create the sound stream
without problem, but SndDeleteStream (?) would hang the device.
We are currently looking for the make/model of the device and cheking a
hard coded list to determine if we should start the sound capture at all.
