When muting my Jabra headset by pulling the mic up, why does it mute me completely and I cannot hear anyone talking?

I have the same issue and I don't think it has anything to do with the Teams or any other meeting tool but Jabra.

Many other (pretty much every Jabra user) reported this issue and Jabra never fixed it. This issue is with every Jabra headset and the only fix is to use the dongle provided with it.

If you lost the dongle and if it's not provided by your office or they're not replenish you with replacement if lost, then you're spending $130 just for the dongle.

BTW, no Microsoft employee can fix this issue since this is the bad software design case from Jabra.

The problems is caused by Intel Smart Sound Bluetooth audio driver.

I had the problem that audio was muted and the mic state was not synced. After updating the driver my Jabra Evolve 75 worked as expected. No more workarounds after updating the ISST driver from the package below.

The driverpackage which has a working driver for me was: https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=0tmc2&oscode=w2021&productcode=latitude-15-3540-laptop&lwp=rt

Extract the package (e.g. with 7-zip) and update update the driver for Intel Smart Sound Bluetooth Audio manually by selecting update driver and choose the path where you extracted the package. You should see version 10.29.0.9947 after the update.

Hope this helps.

HI! it worked for me !! I did a reset and then the problem was fixed. Many thanks!

a workaround is that after you raise the mic boom arm, click on the lower volume button on the headset (while the Arm still up) the audio will come back live.

is not perfect, was not how it was working until early December, but at least is a work around to still have wireless headset (via PC Bluetooth) without the Jabra's dongle plugged on a port,,

============

Update on June 19

Today, Dell pushed to updates to my network driver and the Jabra Went bananas again.

the workaround still work for me. if I raise the Microphone up, everything goes Mute. I click on the headset volume up and down and up and audio come back

I do the Up, down, up because if volume is on Max, the up alone would not bring back the voices, so I do Volume Up and down and up.

Thanks for the workaround!!!!!

Thanks for this tip !
