Unfortunately audio is not working. It was originally but at some point in my troubleshooting process I must have messed it up. The switch itself is working, or at least is making a connection between the solder points on the board when its depressed. Where can I check to make sure its connected to the relay properly? I was using the “ground” labelled hole that is connected to the depth pot. When I get home tonight I’ll cut the trace and double check the voltages with the ground you described.
By the way, thanks so much for all the help and sticking with me thus far.
