The "push-to-talk" is just used when SENDING audio, it has no effect on
receiving sound. Make sure that your sound level (on the Mac) is turned up and
that you are using Sound Manager 3.0 (an extension available from Apple's FTP
site). The bomb you get when trying to use sound is a known bug, it seems to
happen with users who don't have video capture boards installed. Cornell is
working on the problem. In the mean time, you can use Maven with CU to be able
to send audio (if you have a mic that is). Maven is available from

Also, make sure that the other check boxes for RECEIVE and LURKERS is check to
receive audio.

Maven, BTW, is the same as the audio portion of CU - the two where integrated
together. Maven is just standalone.
