I could not get sound to work on Vimeo at all, Trinity 13, and I believe it is the soundboard or the microphone causing the problem.
Zach worked with me over the phone to try some things.
I will call the crew who set it up. They installed the soundboard, and I had the Rode mike.
We will have the service as soon soon after it is fixed. I will let you know.
Thank you for your patience.
