The "talk", "dim/mute", "mono" and arrow navigation buttons on the front of my Quantum are flashing during audio playback.

I've been away for a while but I'm pretty sure I don't remember this happening before and pretty sure it isn't meant to's pretty distracting anyway.

As well as that the top half of the line input 8 meter is jumping along with the the main out meters during audio playback....which definitely doesn't seem right.

I've updated to the latest version of universal control and have updated to the latest firmware.

The INPUT lights should never light up during playback. Make sure there isn't a live mic plugged into it when playing back. I would suggest putting in a ticket with PreSonus if this issue continues.

I ended up getting the unit replaced under warranty after sending it in for repair, not sure what exactly was wrong with it.

I had the same problem. It started about a few weeks after I bought the unit. I sent it back for repair and a week after I got it back it started doing it again. It was replaced with a new unit but I’ve not yet hooked it up.
