Bluetooth connected but no sound

When Bluetooth shows as connected and there is still no sound, the wireless link is up while the audio path used for speech is pointing at a different device, or the Bluetooth profile in use is not carrying voice. Connection status reports pairing. Speech capture and playback follow the microphone and speaker that the operating system and the webcam or conferencing app currently have selected.

How this applies to webcam speech capture

A webcam’s built-in microphone is its own audio input. A Bluetooth headset or speaker is a separate input and output. Conferencing software can take video from the webcam while taking sound from whichever microphone is active. If that selection is the webcam microphone, a muted system device, or a Bluetooth accessory that is paired without an active voice path, the call or recording stays silent even though Bluetooth reports as connected.

Condition that limits this answer

This is a routing conclusion. It holds where the operating system and the app each expose an input and output list, and where the Bluetooth accessory actually presents itself as an audio device. No operating system, conferencing app, or accessory model was named, and no product documentation, measurements, or test results were supplied. The exact control that switches the microphone, unmutes a device, or enables a headset voice profile therefore cannot be stated here as a verified, device-specific instruction.

Supported next action

By inference from how desktop audio routing works, open the input and output lists in system sound settings and again in the webcam or meeting app. Confirm the Bluetooth accessory appears as an audio device, then select the microphone intended for speech. If the accessory is listed only as a paired device and is absent from those audio lists, the connection is up and the voice path is still unavailable for webcam capture until the accessory is presented as an input.
