Hi Newbold,
Thank you for your response.
Since the audio also drops and reroutes to your computer speakers even without the adapter connected, the issue points to how Windows and Teams are managing your audio devices rather than the adapter alone. Here is what you can do on your end to resolve it:
- Set a fixed audio device in Windows
- Go to Settings > System > Sound
- Under Output, choose your headphones as the device, then scroll to Advanced and, under App volume and device preferences, make sure nothing is overriding it.
- Select the device inside Teams
- In Teams, go to Settings and more, then Settings, then Devices.
- Under Audio devices, select your headphones explicitly for both Speaker and Microphone rather than leaving it on the default option.
- This stops Teams from re-selecting a different device when a meeting starts.
- Try a call using Teams on the web
- Sign in to Teams on the web with the same account.
- Join a test call to check the audio.
- Contact Microsoft Support
If the problem continues after working through these steps, the best next step would be to have your IT administrator open a support ticket with Microsoft via the admin center. A technical support engineer can then initiate a remote session, review backend settings, and run diagnostics. If needed, they can escalate the case to specialized engineering teams who are well-equipped to perform advanced troubleshooting and provide targeted solutions.
