Since you mention that you are visually getting an indication that you are
getting sound into the computer then you must have a problem with the way
you have cuseeme configured. ARe you able to open the sound control panel
and record a new alert sound? This will indicate that you are able to input
sound into the computer. If this is the case then you need to look at the
way that you have cuseeme set up. Make sure that the audio window is open.
You may have it set to push to talk, or if it isn't then the default
setting for the squelch may be too high (it is on purpose - move the little
black tick mark down, and whenever your sound level goes above that mark
you'll transmit).
On the ppc7100av we have at school I had lots of problems getting sound to
work. I was able to send sound from a cd, but couldn't get the mic or the
cameras mike to work. Ended up plugging in the stoopid plaintalk
microphone, which has a deformed (therefore proprietary) plug. REally BS
that way apple makes you buy their mic, which incidentally is not currently
available due to shortages.
Anyways, you also need to check the play-through options in the sound in
and out parts of the control panel. It took us a while to get it going, but
audio is fine now...
