Windows Microphone Not Working with Bluetooth Headset: Fix the 'Microphone Not Available' Error
Category: Audio Devices
You’re on a Windows 11 PC with a Bluetooth headset, audio output works fine, but apps show the microphone as not available and won’t let you select it. This is a common windows microphone not working bluetooth issue, and it usually comes down to the headset being stuck in the wrong Bluetooth profile or the microphone being disabled at the system level.
Check the Bluetooth profile and default input
Open Settings > Bluetooth & devices > Devices. Find your headset and click it. Under Audio, you should see two entries: one for output (stereo) and one for input (hands-free). If the input entry is missing, remove the headset and pair it again. Next, go to System > Sound > Input. Select your headset microphone from the list. If it’s not listed, click Manage sound devices and enable it. If it shows as unavailable, that confirms the profile isn’t active.
Verify the microphone in Sound settings
Still in System > Sound, under Input, speak into the mic and watch the input level bar. If it stays flat while the headset is selected, the microphone is muted or the wrong device is active. Click the device and check the volume slider and mute button. Also open Device Manager, expand Audio inputs and outputs, right-click your headset microphone, and choose Enable device if available.
Run a verification test
Open Voice Recorder and record a short clip. Play it back. If you hear your voice, the microphone is working. If not, return to Sound settings and confirm the input device is set as default for both input and communications.
Rollback note
