Monitor section will mute abruptly
 

I have PC and fader pack on a G4 HD3 accel w/10.3.8 PT6.7cs8.
When booting the system the monitor section will only work after you have exercised the switches. But the weird deal is it will just mute for a split second and then back to normal while the sessions is playing.
Also dimming feature is only working on the main unit not the fader pack.
