Hmmmm. I would start by reverting to vat defaults and starting vat manually
to verify that it's working with a standard port, and no conference ID.
I used:

238: VAT-MC-PORT 3456
239: VAT-MC-IN
240: VAT-MC-OUT 63

Start the reflector with the -broadcast switch so you only have to have 1 cusm
client connected.

SunOS 4.1.1 Host > reflect -broadcast

SunOS 4.1.2 host > vat
When the vat window came up I went into the menu and set the format to dvi.

MAC connect to SunOS 4.1.1 host and transmit audio in dvi format.

The vat host doesn't have a microphone, but does have speakers. The audio
transmitted from the client reached the sun's speakers.
