This applied cleanly and installed fine. I have not tested sound at
the jack mounted on the pcb. The way it works here is via the hdmi cable
where the speakers are plugged into the audio jack on the monitor.
I understand that via hdmi would be expected to be of higher quality
output than the jack on the board?

system right now is

For unassociated reasons, need to reinstall as a 13.1-p2 system. I'll
apply the patch to 13.1-p2 and rebuild then post the results back here
