I'm using Teams on an iMac running Big Sur. I use a Plantronics USB headset as my audio device for speaker and microphone, with 'built-in output' set as my secondary ringer. This combination of settings worked fine until a few weeks ago, when the secondary ringer suddenly stopped working. I've tried all the hints and tips I can find online, to no avail.
