Audio Issue when Bluetooth Device Connected

I am having a repeated audio failure when joining MS Teams meetings with a Bluetooth device connected. Windows 11 Enterprise OD build 26100.7623 on Dell Latitude 5450 experiences a system‑wide audio render failure shortly after joining Microsoft Teams meetings when a Bluetooth headset is connected. All output endpoints (Bluetooth and onboard speakers) stop producing sound while audio capture continues to function. Disconnecting devices and restarting audio services does not reliably restore output; a full OS reboot is required. Issue reproduces several times per week. The device I use is a JBL Tune 720BT. Device Manager always states drivers are up to date.

    It seems to be a Bluetooth audio stack issue in Windows 11 rather than Teams itself. The JBL Tune 720BT relies on A2DP and AVRCP profiles, and Dell’s OEM Bluetooth driver often lags behind the generic Microsoft stack. Even if Device Manager reports drivers as current, you should bypass Windows Update and pull the latest Bluetooth and audio drivers directly from Dell’s support site for the Latitude 5450, ensuring the Intel Wireless/Bluetooth package matches build 26100.7623. In parallel, update Teams to the latest desktop client and disable “Allow hardware acceleration for audio” under Teams settings, which has been linked to render failures.

    It seems that you are experiencing audio issues with your Bluetooth headset when using Microsoft Teams on Windows 11. This type of problem can sometimes occur due to compatibility issues with Bluetooth devices or specific configurations in Windows or Teams.

    Here are a few suggestions you can try to resolve the audio failure:

    1. Check for Bluetooth Driver Updates: Even if Device Manager states that your drivers are up to date, it may be worth checking the manufacturer's website for your Bluetooth device (JBL Tune 720BT) to ensure you have the latest drivers.
    2. Disable Exclusive Mode: Sometimes, disabling the exclusive mode for your Bluetooth headphones can help. Go to Settings > System > Sound, then select Advanced > More sound settings. In the Sound dialog box, select your headset, go to Properties, then the Advanced tab, and uncheck Allow applications to take exclusive control of this device.
    3. Restart Teams: If you encounter audio issues after joining a meeting, try restarting the Teams application to restore audio functionality.
    4. Check Windows Updates: Ensure that your Windows 11 is fully updated, as updates can fix various bugs and compatibility issues.
    5. Test with Other Bluetooth Devices: If possible, test with a different Bluetooth headset to see if the issue persists. This can help determine if the problem is specific to the JBL Tune 720BT.

    If the issue continues after trying these steps, it may be necessary to report the problem to Microsoft support for further assistance, especially since it appears to be a recurring issue.
