I've updated the VGA connector PCB to include an audio jack and passive components in place of the second push button. This hopefully matches what you've done with your prototype:I have this wired to desktop PC speakers via a prototype output stage as suggested by Ken (just the passive components). It sounds considerably better!
I'm hoping I've got the pinout for the audio jack correct. I'm planning on using a PJ-322, which seems to be widely available:

This new PCB is the same size (40mm x 25mm) as the original PCB, although I've had to move the VGA connector slightly in order to fit the audio jack alongside.
