You didn't say what version of CU-SeeMe you are using, but I would expect
it is the Cornell version as the White Pine Mac 3.1 version has audio which
works fine under OS 8.1.

In OS 8.1, Apple changed the way they handle "Audio Playthrough". There
used to be a UI item to set it (in the Sound Control Panel). They hid it in
OS 8.1and it is now set based on the audio source selected. BTW, the audio
source now defaults to "None" in the Sound Control panel so you may wish to
verify that you have Mic selected....
