Subscription discussions aside, if you're looking for more feature requests, one thing I'd love is the ability to completely disable audio input devices on OSX. It's something you can't do today. My monitor has an audio in, and shows up as a valid audio input, but there's no mic connected to it. Zoom loves prioritizing it as a device though every time I disconnect my microphone. Likewise other bluetooth headphone audio inputs. Would love the ability to completely remove those as an option in the sound settings.
A system-wide mute button and a system-wide setting to say "this is the only microphone I want to use and when it's muted I don't want another mic to be used" would be nice. Wired headphones often have a physical mute switch, but zoom will happily switch to another microphone the instant you use the mute switch.
Negative - you can only remove audio devices with the audio-midi-setup that have either been added from the feature itself, or are using the underlying APIs for audio. None of my 3rd party audio devices (Sony MX-3000, Sony MX-4000, hdmi audio out, thunderbolt doc audio out) leverage those APIs, leading me to suspect this is actually fairly rare.
You can map default audio input/outputs with the tool, but removing the audio output is a different story.
