Audio Issues
Fix microphone, speaker, and audio problems in InterMIND meetings.
Audio Issues
Microphone Not Working
| Symptom | Likely cause | Fix |
|---|---|---|
| "Microphone access denied" prompt | Browser permission blocked | Click the lock icon in the address bar → set Microphone to Allow → reload |
| Mic icon shows a red slash, no audio level | Mic is muted or wrong device selected | Click the arrow next to the microphone button in the control bar → pick the right device |
| Audio level indicator stays flat when you speak | OS-level mic permission blocked | macOS: System Settings → Privacy & Security → Microphone → enable browser. Windows: Settings → Privacy → Microphone |
| Mic works in other apps but not InterMIND | Another browser tab is holding the device | Close other tabs that may use the mic (Zoom Web, Google Meet, etc.) and reload |
| Bluetooth headset connects but no audio | Headset is in low-quality (HFP) mode | Disconnect and reconnect the headset, or switch to wired |
No One Can Hear You
| Symptom | Likely cause | Fix |
|---|---|---|
| Your audio level moves but others hear silence | Wrong mic device routed | Open Settings → Devices → select the correct microphone |
| Others hear muffled/distant audio | Laptop's far-field mic instead of headset | Switch device in the control bar; physically move closer to the laptop if no headset |
| You speak but only one participant doesn't hear you | That participant has their speaker muted or wrong output device | Ask them to check their speaker selection — not your issue |
You Can't Hear Others
| Symptom | Likely cause | Fix |
|---|---|---|
| Total silence from everyone | Browser tab muted (right-click tab → Unmute) | Unmute the browser tab |
| Silence from one participant only | They are muted, or their mic is broken | Check their mic indicator in the participant list |
| Translation audio playing but no original voices | Translation replaces original audio by design | This is expected — see Real-Time Translation |
| Volume too low even at 100% | OS output is low or wrong output device | Check OS sound settings; switch output device |
Echo or Feedback
| Symptom | Likely cause | Fix |
|---|---|---|
| Everyone hears their own voice with delay | Someone in the room is using a speaker without a headset | The offender should mute, switch to a headset, or use the Echo cancellation toggle in browser audio settings |
| Crackling, popping, or robotic voice | Bluetooth bandwidth saturated, or another app using the mic | Switch to wired audio; close other audio apps |
