With the 660AV or 840AV, you need to switch off the Express Modem control
panel before you can send audio. It doesn't matter if it's installed and
in your Control Panels folder, provided it is switched off *before* you
try to send CU-SeeMe audio. Somebody once told me he was able to receive
a fax via a Geoport modem while sending CU-SeeMe audio on his 840AV, but
I have never been able to get my 840AV to send audio with the Express
Modem CP switched on.

I think Michael is mistaken on this one. I have *never* come across the
SPB -227 error message except with audio problems.
