220-1102 Question 601
Single answerBluetoothA user reports that a Bluetooth headset worked previously with their Windows 11 laptop, but after replacing the headset battery, the laptop can see the headset in Bluetooth settings and pairing completes successfully. However, audio still plays through the laptop speakers and the headset does not appear as an available playback device in Sound settings. The user needs the headset working as quickly as possible for a video call. Which of the following should the technician do FIRST?
- A
Remove the headset from Bluetooth devices and pair it again so Windows can reinstall the appropriate Bluetooth audio profile/services
- B
Disable the laptop speakers in Device Manager so Windows is forced to send audio to the headset
- C
Update the laptop BIOS because Bluetooth audio routing problems are usually caused by firmware incompatibility
- D
Increase the Bluetooth adapter transmit power in Windows advanced settings to improve audio device detection
Show answer and explanation
Correct answer: A
Explanation
This scenario tests practical Bluetooth troubleshooting in Windows. When a Bluetooth headset pairs successfully but does not appear as a playback device, the issue is often not radio connectivity but incomplete or incorrect installation of the Bluetooth audio functions during pairing. Best practice is to start with the least disruptive and most likely fix: remove the device and pair it again. In Windows, Bluetooth audio devices rely on the proper association of supported services/profiles so the OS can expose the headset as an audio endpoint in Sound settings. A technician should avoid unnecessary escalations, such as BIOS updates, before trying standard remediation steps. This aligns with common Microsoft troubleshooting guidance for Bluetooth devices: verify Bluetooth is enabled, remove and re-add the device, and confirm the device appears correctly in audio settings.
- A. Correct.
Correct. If a Bluetooth headset pairs but does not show up as an audio playback device, a common real-world cause is that the required Bluetooth audio services/profiles were not bound correctly during pairing. Removing the device and pairing it again is an appropriate first troubleshooting step because it is quick, low risk, and often causes Windows to reinstall the headset as an audio endpoint using the correct Bluetooth services.
- B. Incorrect.
Incorrect. Disabling the internal speakers does not fix the underlying issue that the headset is not registered as an available audio playback device. Windows cannot send sound to a headset that is paired but not properly installed with the necessary audio function. This is a plausible choice because users often think output routing is the only problem, but here the headset is missing from playback devices entirely.
- C. Incorrect.
Incorrect. BIOS updates can help with some hardware compatibility issues, but they are not the first step for a headset that was previously working and is now pairing without exposing audio playback. This would be overly invasive and time-consuming compared with re-pairing the Bluetooth device.
- D. Incorrect.
Incorrect. Windows does not provide a standard setting to manually increase Bluetooth transmit power for this purpose, and range/power is not the symptom described. The headset is already discoverable and pairing completes, so the problem is not basic radio detection.
