Thanks for your feedback, Gary.
I actually did download and install the 1.2.2 software update package from the AJA website, and I have the “lock input audio gain to unity” box checked.
I wonder if it has something to do with my Tannoy Reveal Active speakers (which haave no volume control knob on the speakers?)
It seems strange that I have to set the output volume on the Mac to 1% or 2% to get a normal sound output level from the speakers. I know that this shouldn’t be.
Any other ideas?
Thanks,
Khashyar
