Re: [SoX-users] recording audio on a mac

OK, thanks. It doesn't tell us to much. It does say hardware is
defaulting to 16-bit 44100 sample rate 2 channels... which is good.
For unknown reasons, SoX processes no samples though. It could be as
simple as under-run not handle gracefully when first opening buffer
but just needs some machine time with a debugger from here.
Sorry, no solution at this time.
