Bluetooth audio can look connected while the first tone is silent, delayed, or routed to the wrong device. Test gently and give the device time to wake.
Put headphones on, set volume low, and play the Both tone first. Bluetooth devices can sleep between sounds, so the first tone may be late or silent. Wait a second and play it again before changing deeper settings.
If nothing plays, check the operating-system output device. Browser pages often use the system default output unless the browser exposes an output picker.
Play Left, then Right, then Both. If the sides are reversed, check headphone orientation or cable routing. If one side is quieter, check balance settings, earbud seating, audio interface routing, and whether the device is in a low-quality headset mode.
Some Bluetooth headsets switch profiles when the microphone is active. That can make music or tones sound thinner during calls. Test the speaker output and microphone separately, then test inside the meeting app.
Meeting apps can choose their own speaker output. If MicAndCam plays through the Bluetooth device but the meeting app does not, open the app audio settings and select the same headphones or speaker there.
If the app has separate speaker and ringtone settings, test both. A ringtone can play through laptop speakers while call audio uses headphones.
Many Bluetooth devices sleep or switch modes after silence. Wait a second, confirm the output device, and play the tone again at low volume.
Some headsets switch to a communication profile when the microphone is active. That can reduce speaker quality compared with normal music playback.
