I have seen several posts about this issue with no real resolution. Did anyone ever figure out why this happens? In my case the limiter activates upon loading a track or when I jump to a certain part of a track using the needle search or a mouse. I have tried all the variations of settings including turning off auto gain, normalizing while recording etc. I can turn off the "bug" by pausing and then unpausing the playing track. Also, this doesn't just happen when recording. I can watch the output get smashed even by just using the software without a controller attached which means it's the software. Attached is a screenshot from audacity.

BTW all output levels are green...
