Teams not showing as muted

I am seeing this same issue again here in September 2022. For about 18 months prior to August 2022, the hardware mute status of my Jabra Evolve 75 UC headset was always in sync with the software mute status in both Microsoft Teams and Zoom. Sometime in August 2022 this changed. Now the mute status in Microsoft Teams is in sync with the mute status of the headset only about 50% of the time. The sync between the hardware mute status and software mute status in Zoom is still right 100% of the time, pointing to the hardware functioning properly and there being a software-level issue.

Means that if I want to talk on a call in MS Teams I can't just lower the boom arm down, I also have to check what the mute status is in Teams and manually click on the unmute button if the two are not in sync (which is a problem about 50% of the time). It is terribly distracting for my calls, having to worry about the mute status in the software being different from the hardware.

This started happening in August 2022, though I can't be sure it first became an issue with the MS Teams 1.5.00.22362 release. Here is more information on the versions of things.

• Computer: MacBook Pro, 16-inch, 2021 (M1)
• OS: macOS Monterey 12.5.1
• Running Jabra Direct version 6.3.22201. Preferred Softphone is set to Microsoft Teams in Jabra Direct settings.
• Jabra Evolve 75 UC with firmware version 2.38.0
• Jabra Link 370 with firmware version 1.87.0

I have tried unpairing the Jabra Evolve 75 from the Jabra Link 370 and then re-pairing them. No change to the observed issue and MS Teams is still out of sync with the mute status of the hardware about 50% of the time.

I have tried connecting the Jabra Evolve 75 directly via bluetooth instead of through the Jabra Link dongle. No change to the issue.

I have tried a USB wired connection for the Jabra Evolve 75. This does seem to improve the frequency of how often the mute in MS Teams is in sync with the hardware to about 75% working and 25% failure, but even at 25% failure this is a problem.

I have tried killing the Teams app and restarting it. I have tried killing the Jabra Direct app and restarting it. I have tried rebooting the Mac. The issue remains.

Also note that this all works perfectly in the Zoom application. 100% of the time the Zoom mute status is fully in sync with the mute status of the Evolve 75 headset. Raise the boom arm on the headset, Zoom shows mute is applied. Lower the boom arm on the headset, Zoom shows mute is not applied.

I realize the headset is the UC and not the MS version, but this issue with the software mute status not being in sync with the hardware mute status was not a problem over the previous 18 months. Seems like a software level issue happened in this time causing this issue.
