Ruslan Prokopchuk ae7fc0177b fix microphone example fill with zeros case 
Usually when microphone example is run you never hit buffer underflow and "fill with zeros" branch is never executed. But when it's executed it fails with "invalid value" because of checks performed on frame_count. This platform-independent check 8094dc5249/src/soundio.c (L447) sometimes passed because unitialized local frame_count have arbitrary value, but this CoreAudio one 8094dc5249/src/coreaudio.c (L1078) is not passed, and "fill with zeros" scenario always fails on MacOS.

Andrew Kelley d168a7d192 ALSA: better device detection 
* Don't suppress sysdefault.
 * If default and sysdefault are missing, use the first device as
   the default device.
 * In sio_record example, don't segfault when device not found or
   probe error.
 * Workaround for Raspberry Pi driver that incorrectly reports
   itself as Output when it is actually Input.

See #44.

Andrew Kelley 7238d29666 sample rate is exposed as a list of min/max pairs 2015-08-08 14:44:31 -07:00
Andrew Kelley c381526205 callbacks supply min and max frame count parameters 
This changes the semantics of the callbacks so that instead of
a single `requested_frame_count` or `available_frame_count`,
the callbacks get a minimum frame count and maximum frame count.

The callback must write at least the minimum or get an underflow.
The minimum will be 0 on ALSA, PulseAudio, and Dummy, and will
equal the maximum on CoreAudio and JACK.

This ensures optimal behavior regardless of buffer size.
