My 16.4.2 Classic mixer loses sound when I connect to my Mac through Firewire, I am getting signal into the mac, and universal control, meters are showing signal coming in, but all my sound is lost on the mixer. and I can't playback to the mixer.. after plugging into firewire, I must shut down the mixer in order to get signal to go to the mixer from inputs, sometimes it takes long periods of time for the mixer to get signals from my microphones'. The Mixer used to work just fine, but I took a break from using it for a while, and now it does this. I am running the current Drivers . Driver version 4.2.1. 46437 5875
Presonus 16.4.2 Classic Mixer
