[jitsi-users] Mac OS X Mavericks - No Sound on 2.4 or Latest Nightly

Jitsi doesn't make any noise on Mac OS X Mavericks (Clean install).
Tried on two separate machines. Using CoreAudio on internal mic and
speakers, the mic is working and sending audio to the remote machines
(Linux and mac) but no audio is coming out. Snow Leopard isn't a problem.

Using the 1.6 JRE that Jitsi caused to be downloaded on first run.

Can anyone else duplicate this?
