When my Luna Display module is plugged into the mini-display port of my iMac (Retina 5K, 27-inch, Late 2014) running macOD Catalina 10.16.6, the default swoosh sound when sending mail goes away. Removal of the Luna Display module restores this sound. Has anybody else noticed this happening to them? This is the kind of think that many people might not even pay attention to but none-the-less it does happen to me.
Astropad technical support has been cooperative in trying to help me but they are not able to reproduce the problem. While not a show stopped it does bother me not hearing that sound to confirm that an Apple eMail has been sent.
Any takers on this one???
