3022.0. "A2300 and Bye Bye Audio" by DICKNS::MACDONALD (WA1OMM 7.093/145.05/223.58 AX.25) Mon Oct 16 1989 11:53

I installed an A2300 genlock in my 2000 the other day. However, when I
plugged my RGB cable into it the sound to my Sony 1311 monitor
disappeared and was replaced with TV audio. After dissecting the cable
and looking at the 2300 circuitry and circuit diagram, I discovered that
Commodore failed to provide +5VDC to pin 23 of the 2300's RGB port.
The 1311 requires +5VDC apparently to drive the audio section when in
RGB mode (front panel switch). +5VDC is normally supplied on pin 23 of
the 2000's RGB port.

A couple dabs of solder to add a jumpre on the 2300 solved my problem.
