I just did a clean install on my Mac Pro of Mojave (2013 trashcan). I downloaded the latest version of UC, and when I ran it, it prompted me to upgrade the firmware from 1.04 to 1.05.

Now I have this issue where, after a random amount of time, I will start hearing crackling, which slowly grows worse till the audio is completely breaking up. A reboot will fix it temporarily, but I'm wondering if there's a way to roll back the firmware? Anything else I can try?
