When asking questions of this sort, it's customary to
provide more intormation. Platform? OS Version?
Max/MSP/Jiitter version numbers?
A patch that demonstrates the behavior would
also be helpful. Smallest version you can make.
This one's a bit larger than that, but it works fine
for me 10.4.6, current versions available for
download at 8:30 AM CDT [I'm normally running
betas on this machine, so I downloaded to check].
The simpler test for me (i.e. the one I actually did)
was simply to instantiate a jit.qt.movie object with
an @autorestart 1 attribut and read in a movie I
know has an audio track. I heard nothing, which
means it's working fine. Jitter Tutorial 1 page 1
describes why this is the case.
