How do I stop teams from turning my headset volume up to 100% in the "App volume and device preferences" before each call?

The "Don't sync device buttons" worked fine, until today. Now I have Teams hurting my ears EACH TIME I take a call, again with no way to fix it permanently. Microphone volume from new teams app is neither working anymore (it did until today). No matter where you set it, it keep blasting my ears, except going to the stupid Windows settings volume mixer to decrease the volume there, for each call. No, windows mixer is not working either.
This is getting old and deteriorating over time. The old workaround (disabling sync device buttons) does not work anymore. Is Microsoft really wanting to hurt our auditory system? Anyone willing to raise a lawsuit against Microsoft for these changes?

I definitely have this issue as well...and it's maddening. I'm on a desktop, wired speakers, everything set the way I want it, then Teams blasts out on calls which makes me jump almost every time. This is nuts, there should be a switch in Teams that says 'Do not change volume on anything, EVER'.

Tried just about every solution in this and other threads and still doesn't work right and blasts volume (so if I was listening to something and place a call the volume blows out). Tried volume mixing settings, Communication device settings, app volume, device settings, exclusive device access, etc. Nothing fixes this and it's unbelievable there's no fix for this after all the complaints.

This seems to be related to the new Teams client, didn't have this before. There needs to be a switch in Teams to stop this behavior (this problem only affects Teams, nothing else).

Microsoft--this isn't a volume level issue, a device driver, some deeply buried function, it's a BUG in Teams (or at least a feature you have no exposed UI for).

Still a prevalent issue 1-9-24. Would love to see @Microsoft jump back into the conversation

I've tried this but it didn't work for me. Still going to 100% volume for teams (both new and old) and deafening even if every other volume bar (including the master) is on 1%

I'm having this exact same problem and it is very annoying. I keep hanging up on people trying to use the volume knob to turn down the sound every time I get a notification.
