The following plays a 441 Hz tone directly into the audio driver.
If you alter this code, it is important not to block requests from the
audio driver for more samples. While this source runs in userspace,
and it supplies data from userspace, the requests for samples seem to
be coming from a hardw

In this particular case, all I wanted was to learn how to spit audio
samples directly into the sound driver.
My input does come from another thread, reading ogg vorbis, flac, wave
or mp3 files that write into a circular buffer. When the buffer is

Maybe my experience is simply too narrow to be able to know how to resolve
this issue, but I'm seriously confused by an issue I'm seeing in my Cocoa
