Perhaps system too busy, disk not fast enough?
before doing a play-back, run "iostat 1" in another window
interesting. the stutter certainly correlates to minor amounts of disk
i/o. when there is no stutter, there is nothing to report. but a minor
amount of wait/busy lines up with the stutter.
# iostat -znx 1

Incase iowait is too high, try moving the files with the playback
sound/speech upon tmpfs (thus eliminating the hard disk)
That's worth a shot. I dont have big enough tmpfs to copy the whole
sounds spool, so i:
# cd /var/lib/asterisk/sounds/en/
# mkdir /tmp/sounds
# ln -s /tmp/sounds tmpfs
# cp mysound.ulaw tmpfs
Playback(tmpfs/mysound)
But it didnt help, still randomish stutter lining up with the disk.
this is a great help, at least i can start hacking at things now.
Thanks,
