Log Message:
pad(4): run the callout if the buffer is saturated instead of returning
reverts to the same behavior as in -8 and -9. prevents immediate failures
and device timeouts if there's a slight delay in the buffer being
consumed.
this is reproducible with the example in the man page that uses
ffmpeg to record the output of audioplay:
$ ffmpeg -f s16le -ar 44100 -ac 2 -i /dev/pad0 output.wav
$ audioplay -d /dev/audio1 input.wav
if output.wav already exists, ffmpeg will prompt for confirmation
to overwrite as soon as audioplay starts, causing a noticable delay,
followed by a write failure that causes audioplay to immediately
exit.
