Also -- look in QTSoundFilePlayer.m for the definitions of the

one or both of them should decrease the chance that you'll get
dropouts. The default values work fine on my machine, but I don't
imagine they are optimal under all conditions -- it's up to you to
figure that out.
Couldn't you dynamically not add more buffers if you notice you are
having
underrun or dropouts? I think your default buffers are 128K that
should be
more then enough?
If you want to try adding something like that, the code is all there,
go right ahead! I think it's probably unnecessary and would be
difficult to get right in all cases, but you are welcome to try.
In any case, try increasing the buffer size using the #define first, to
see if that solves the problem. There is no point in trying some
dynamic buffer scheme if that is not even the real problem.
There is no other activity on my computer so it couldn't be thread
issue.
I even got major interruption sometimes like 1 second
So haven't figure out why yet
Well, me neither. Like I said, it works OK for me. What happens when
you try playing AIFF or MP3 files?
