Follow-up Comment #2, bug #54668 (project octave):
Thanks for responding Mike. Yes, that is correct, I can get the posted code to
work with the built-in sound card on my desktop computer (HPZ420, Win7,
Realtek sound). With the PreSonus Audiobox 96 I get the error "audiorecorder:
unable to open audio recording stream" with MME drivers. I don't know if this
is being passed up from PortAudio or if it is coming from Octave. I have had
it work with the Audiobox and DirectSound drivers (in the sense that there are
no error messages) but the recorded data is all zeros. That seems more like a
problem with the Octave interface to PortAudio, but I am not sure. I did find
on the Audacity site in a discussion about PortAudio they say that Windows
DirectSound and MME do not support 24 bits, so perhaps that is the underlying
problem. But these things are time-dependent and I don't know if this is true
for the current version of the Windows drivers and the current version of
PortAudio. I also don't know what version of PortAudio is in Octave 4.4.1. It
is a little over my head to try to look at the Octave code.
