Teams has a notice that it pops up if you're talking and on mute, and there's another for if you're not on mute but your mic is producing no signal (mic has it's own mute). I find those super helpful, personally.
I am muting because I don't want the sound in my room broadcasted... if it was silent, I wouldn't have to mute!
Not to mention push-to-talk has solved this issue for almost a few decades now.
Because
1) most group calls that need people to be on mute most of the time are useless, boring, snooze fests, most attendees don't care about, so those 'professionals', who are caffeinated zombies half asleep, will space out and forget the status of their mic within 10 seconds of toggling it
and
2) most chat apps suck at drawing attention to the status of the mic and, if you have multiple monitors, you can be staring at one monitor (Jira, reddit, Redmine, HN, VS Code, etc.) while the chat app and the status of the mic is being displayed on another monitor where you're not looking
It's a mistake super easy to make. Still, better be safe and make the mistake of being muted all the time, than forgetting to mute yourself and have participants hear something you didn't want them to hear.
Ideally I'd want a feature that gives the image on all my monitors a nuclear red vignette, or something like that, whenever my mic is hot, so I don't have to keep paranoidly glancing at the mute toggle every couple of minutes, to make sure my mic is still muted, so they can't hear me mumbling on how incompetent management is and on how useless this meeting is.
Still, PTT is the solution, preferrably in hardware. Not supported in sw anyway by e.g. Teams. In hw it keeps the mike-on symbol lit, and the device powered. Always having to push prevents ever forgetting to do so.
Discord's input handler sucks, uses semantic keys, not keycodes. Can't be mapped to an otherwise disabled capslock. TS and mumble can do that. Compared with those Teams audio looks like a toy.
I know people that literally retired early when they were forced to use PCs in the office. Over 30 years later, many people can barely use the most basic features of their computer. All to say, I’m not surprised this is an issue and I don’t see people as a whole digging their way out any time soon.
Some people don’t intuitively track the state of the video conferencing microphone, especially if they have cognitively involved jobs or lots of distractions. Mine are 1) the inability to resist that little self esteem boost from disdainfully highlighting inanity of other people’s shortcomings, and 2) making snide comments.
They’re both super obnoxious but I’m working on them.
It also can keep the Teams mute status in sync as long as I don't touch it in the app myself (I believe through Teams detecting whether the mic interface is marked as muted or not, so it isn't exclusive to my mic).
Personally I just have a headset with hardware mute functionality and a big red circle showing me it's muted. It remembers its muted status, so I just mute it by default and default my OS to use the headset's mic. That way I know quickly and easily when I'm muted and when I'm not, though even then I have small mistakes in the mornings when I'm tired. Over time I've optimized my meeting workflow because my company has gone all remote and I'm in a lot of meetings.

For me, with this method, text chat works a bit (often forgets chat history on reload). Notifications get dropped all the time. No video conferencing at all. Sometimes I have to discuss with colleagues, why my teams acts weird.
