Aircurve ASV Popping Sound(not water)

I keep having intermittent issue with a single popping/click sound on inhale and exhale. It appears to be the humidifier chamber because I can stop the sound by holding the chamber closed tighter or by putting force to pulling the lid and bottom away from each other. Sometime doing that will keep it quiet again for awhile or at least long enough for me to fall back asleep. It seems like inhale/exhale is causing lid movement resulting in the sound thus annoying me enough that I can’t get to sleep or fall back to sleep

Any thoughts on a remedy? Should I order a new chamber to see if the fixes it?

Have you removed the humidifier lid gasket..cleaned it and carefully replaced it?

I haven’t. Didn’t even know I could. I will give that a shot.
