# Why can’t I switch my camera or microphone during a live interview?

During a Live interview, candidates may need to switch audio or video devices, for example, changing from a built-in microphone to a headset or selecting a different camera. If device switching does not work, it is usually due to browser permission restrictions, device conflicts, or system-level limitations.

This article helps candidates identify the cause and resolve the issue quickly.

### 🔎 **Troubleshooting Common Issues**

| What might be wrong?                            | What to do                                                                                                                     |
| :---------------------------------------------- | :----------------------------------------------------------------------------------------------------------------------------- |
| New device not detected by the browser          | Connect the camera or microphone **before** opening the interview link. <br />Refresh the interview room to re-detect devices. |
| Camera or microphone permissions blocked        | Click the `lock icon` in the browser address bar and set camera and microphone permissions to `Allow`, then reload the page.   |
| Device in use by another application            | Close Zoom, Teams, Meet, Discord, or any app using audio/video devices before retrying.                                        |
| Unsupported or outdated browser                 | Use the latest version of Chrome, Edge, or Firefox. Avoid in-app or embedded browsers.                                         |
| Device switch option unresponsive mid-interview | Keep the interview tab active and avoid switching tabs while changing devices.                                                 |
| OS-level permission restrictions                | Check system privacy settings and ensure the browser is allowed to access camera and microphone.                               |

  ### **Additional Tips:**

  * Keep backup devices (wired headset or alternate webcam) ready.
  * Avoid Bluetooth devices with low battery, as they may disconnect unexpectedly.
  * If switching fails mid-interview, inform the interviewer via chat before refreshing the page.
