Windows issues

Symptoms:

• The audio quality on your computer is low (stuck in HFP mode)
• Opening sound settings or communication apps causes the computer to hang or reboot when a dongle or headset is connected to it
• Unable to pair the headset to the computer through the dongle or Bluetooth
• Headset continuously disconnects when connected to the dongle
• Mic or audio does not work when the headset is connected through Bluetooth

Resolution:

NOTE: These steps only apply to Intel-based computers.

1. Search for Device Manager in Windows Search and open System Devices.
   
   
2. Find one or both of the drivers below, right-click on them and select Disable device. Make sure you disable only these drivers:
   • Intel(R) Smart Sound Technology (Intel(R) SST) Audio Controller
   • Intel(R) Smart Sound Technology (Intel(R) SST) OED
     
3. In the Drivers list, locate your headset, right-click on it, and then select Uninstall Device.

macOS issues

Wireless headsets have no audio output or mic function after reboot/sleep/cold boot or replugging to the system

1. Power off your headset and turn it back on.
2. Make sure your headset is connected to the receiver and is within range.

Headset works on Bluetooth, but the audio/button function has a problem

If your headset has a problem with its audio/button function when connected to Bluetooth:

1. Navigate to the following folder, and delete all plugins:
   ~/Library/Audio/Plug-ins/HAL/
2. Once deleted, restart your computer.

Volume change does not sync with system volume or syncs slowly. I sometimes hear two tones when I reach max/min volume

• If changing the volume on your headset does not sync with the system’s volume, update to the latest version of macOS.

Windows and macOS issues

Microsoft Teams application LED or button does not work

1. Make sure your device has the latest firmware (you can update through Logi Tune).
2. Uninstall the Teams app, and then remove the remaining files from the folder below:
   • Windows: C:\Users\<user-name> \AppData\Roaming\Microsoft\Teams
   • macOS: ~/library/Application support/Microsoft/Teams
3. Reinstall Teams, and check if you have any pending updates
