What Audio Devices Are Connected?
View all audio input and output devices detected by your browser — microphones, speakers, headphones, and audio interfaces — all enumerated locally without installation.
This tool uses navigator.mediaDevices.enumerateDevices() to list all audio input (microphone) and audio output (speaker/headphone) devices currently connected to your system, including their labels and device IDs.
Browsers require microphone permission before revealing full device labels. Without permission, devices are listed but their names appear as empty strings to protect user privacy.
No audio devices detected.
What Do Your Results Mean?
| Result | Range | Meaning |
|---|---|---|
| Good | Multiple input and output devices listed with names | Your audio devices are properly detected and accessible. The browser has permission to show device labels, making it easy to identify each device. |
| Warning | Devices listed but labels are blank | Devices are detected but microphone permission has not been granted. Allow microphone access when prompted to see full device names. |
| Bad | No audio devices found | No audio devices are connected or your browser cannot access them. Check physical connections, system audio settings, and browser permissions. |
Common Issues and How to Fix Them
Device labels are blank or show generic names
Grant microphone permission when the browser prompts you. Without permission, browsers hide device labels for privacy. Click the lock icon in the address bar to manage permissions.
A connected audio device does not appear in the list
Check that the device is properly connected and recognized by your operating system first. Try unplugging and re-plugging the device. Also restart your browser, as device enumeration may cache results.
