The sound problem seems to be a large mess. I have also had the same
problem here. I just received a message from developer Larry Chace
( The audio is being worked on by Maven, the people
whose audio software is used in Cu-SeeMe.

As for the MacTCP Watcher, I can confirm your observations. I don't know
how they are sending Cu-SeeMe.

I would like to encourage you to post your audio problem to the group. I
have had MANY people saying they have the same problem e-mail me directly
rather than posting to the group. I think our Mac audio problem is
under-appreciated. Please help correct that.
