Hi, my name is Kelly, and I'm an independent consultant and I'm here to help.
Here are some troubleshooting steps you can try to fix the issue:
Unpair and pair the Jabra Elite 65T again. Go to your computer's Bluetooth settings, and remove the Jabra Elite 65T from the list of paired devices. Then, put your headset in pairing mode and try pairing it again.
Update your Bluetooth drivers. Go to your computer manufacturer's website or the Bluetooth adapter manufacturer's website to download and install the latest Bluetooth drivers.
Try disabling the Hands-free AG Audio profile. In the Sound settings of your computer, right-click on the Jabra Elite 65T and select Properties. Go to the Services tab and uncheck the Hands-free AG Audio profile. Click Apply and then OK.
Check the default audio device settings. In the Sound settings of your computer, make sure that the Jabra Elite 65T is set as the default playback and recording device. Right-click on the Jabra Elite 65T and select Set as Default Device.
Try resetting the Jabra Elite 65T. Put your headset in pairing mode, then press and hold the button on the headset until the LED flashes purple.
Check for firmware updates for the Jabra Elite 65T. Go to the Jabra website and download the Jabra Direct software. Connect your headset to your computer and run the Jabra Direct software to check for firmware updates.
I hope these steps help you resolve the issue. Let me know if you have any further questions or concerns.
