I’m on MacOS 15.3.2, Cursor 0.48.2 and never heard the Ding.
Maybe related: Cursor once asked me to allow Microphone(?!) access, which I denied. I have Boom3 running, which needs Mic to enhance sounds (but not Cursor itself). Switching Mic access on for Cursor (System settings) did not help.
Please fix or assist @deanrie , important feature for me.
