[vorbis-dev] Jittery Audio Output When Calling ao_play() function.

I've gotten my Ogg application to seek without crashing (thanks to all for
their suggestions) and I can get audio out of the speakers, but there are
spots throughout the playback where the audio is jittery.  It's very
prevalent at the beginning of playback, then appears intermittently
throughout the rest of the audio file.  I've played the same file back with
ogg123 without problems, so it's something that I'm not doing right in my
code.

It basically gets into a loop and gets the PCM via the ov_read() function,
then dumps it to the ao_play() function for output.  I'm monitoring the
return value from the ov_read() call and it isn't reporting any errors.  Any
ideas on what my be the culprit, here?  I believe it to be in the ao_play()
call, so possibly a problem with how I'm accessing my audio device.

Thanks,

Greg
