No Sound!

[Bramble]

Hi all,
I've just loaded pro tools LE 7.4.3 onto my macbook and I can't seem to get any playback sound. Has anyone had this problem? Is there something I have to tweak in my systems preferences?
The internal speakers are working fine for all my other applications.
Many thanks,
Billy

ahem , its tdm land here ,
and also pt LE needs its hardware , so its not possible to
play with pt-LE out of your internal loudspeakers,
where ever you found your software , there should be also the hardware..
or not ,
if you have a small (micro) or larger (m box ) bricket anywhere lying
try to connect it with your laptop,
at least you need then a headphone or external speakers.
