This has happened a few times of late. We have the Audio processing module set up with only the AGC enabled, no compression, no EQ. It's on the Hard preset, no manual tweaks.
A show started playing today and I noticed the level was quite low. An hour later I checked again, it was still low. I went into PlayIt on the remote PC and into Audio Processing. Didn't have to touch anything, as soon as I went to the AGC window the audio picked up.
But I thought it was supposed to do that on it's own ? Obviously the AGC did work, but only when given a prod by me opening the window. It realised then, but not when the audio started.
Still doing this. Only way to correct the low volume is to go into the plugin, but I don't have to touch anything, it seems to realise I've caught it napping - again... :-)
