A camera or microphone that works in another app can still be blocked for one website. Use the fictional diagnosis cases and one-site checklist to find the cause without changing every site's access. The companion video's Chrome panels are labelled illustrative diagrams; no real camera, microphone, or site permission was changed for them.
Identify the exact website and device
Read the full hostname in the browser tab where the problem occurs. Camera and Microphone are separate permissions. Decide which one is failing. Do not grant access to a site you do not trust.
If Chrome's address bar shows one hostname but you changed a different site's entry, the test is inconclusive. A working camera in another tab also does not prove the problem site's permission is allowed.
Inspect the site in desktop Chrome
- Open Chrome Settings > Privacy and security > Site settings.
- Under Permissions, open Camera or Microphone, whichever fails.
- Review the sites that are allowed and not allowed. Select the entry for the exact website.
- If the website is blocked and you trust it for a camera or microphone task, change that site's affected permission to Allow. This is your choice; the practice exercise does not require granting permission.
- Reload the chosen site. Return to its Chrome entry and confirm the state shown there. Keep the global default and unrelated site entries as you intended.
If the site is already allowed, do not keep toggling it. Follow the next branch.
Separate the other two causes
In Chrome's Camera or Microphone settings, check which device is selected. With multiple cameras or microphones, an allowed website can still point to the wrong input. Choose the intended device, reload the site, and inspect the site's own preview or input meter.
If that preview is still blank or silent, check the meeting page's mute control, any hardware mute switch, and your operating system's camera or microphone access for Chrome. Restart the call or Chrome after changing system access. Chrome site permission alone does not prove that the physical device is working.
| Fictional case | Best first check | What counts as a result |
|---|---|---|
| A: this site is listed as blocked | Exact site's Microphone entry | Its state changes only if you choose to allow that trusted site |
| B: site allowed, wrong mic selected | Chrome Microphone device selector | Intended input appears in the site's own meter |
| C: site allowed, no signal | In-site mute and operating system | Preview or meter works after the actual cause is corrected |
| D: different website works | Full hostname in each entry | Change only the intended site's permission |

Common questions
Should I switch Chrome's global default to Allow? For a one-site problem, first inspect the exact site's entry. A broad default changes the scope of future requests and may not address a wrong device or system block.
The site says “allowed” but no one hears me. Is the guide wrong? “Allowed” confirms a browser permission state. It does not confirm your input device, mute switch, operating-system access, or a working call. Check the site's own preview or meter.
Can I reverse a site grant? Yes. Return to that site's Camera or Microphone entry and choose the permission state you want.
