Hello, I am Henry and I want to share my insight about this issue
The root cause of this issue lies in how Bluetooth profiles are managed by Windows. When you connect your AirPods Pro 2, Windows creates two separate audio devices for them:
- AirPods Pro 2 Stereo (Headphones): This uses the A2DP profile. It delivers high-quality stereo audio for listening only. It has no microphone channel.
- AirPods Pro 2 Hands-Free AG Audio (Headset): This uses the HFP/HSP profile. It delivers lower-quality, monaural audio but supports both the speaker and the microphone. This is the mode required for calls.
Please refer these solutions below
Solution 1: Manually Select the Correct Device in the App Settings. You need to tell Teams and WhatsApp explicitly to use the "Headset" device for calls.
- Open the Microsoft Teams desktop app.
- Click on the three dots (...) next to your profile picture and go to Settings.
- Navigate to the Devices section.
- Under "Audio devices," you will see dropdowns for Speaker and Microphone.
- For Speaker, select Headset (AirPods Pro 2 Hands-Free AG Audio).
- For Microphone, select Headset (AirPods Pro 2 Hands-Free AG Audio).
- Make a test call in Teams to confirm it works. The audio quality will drop to mono during the call, which is expected.
- You will need to find a similar audio device setting within the WhatsApp desktop app.
Solution 2: Set the Default Communication Device in Windows
- Right-click the Speaker icon in your taskbar and select Sound settings.
- Scroll down and click on More sound settings. This will open the classic Sound control panel.
- Go to the Playback tab.
- Find Headphones (AirPods Pro 2 Stereo). Right-click it and set it as Default Device.
- Find Headset (AirPods Pro 2 Hands-Free AG Audio). Right-click it and set it as Default Communication Device.
- Now, go to the Recording tab.
- Find Headset (AirPods Pro 2 Hands-Free AG Audio). Right-click it and set it as both Default Device and Default Communication Device.
- Click OK and restart Teams and WhatsApp.
Hope this helps you.
