Step 1: Check Site Permission
Chrome requires per-site permission for microphone access.
- On the website that can't access your mic, click the 🔒 lock icon (or ⓘ icon) in the address bar
- Find "Microphone" in the permissions list
- Change it from "Block" to "Allow"
- Refresh the page — the site should now prompt for mic access
Step 2: Check Chrome Global Settings
- Type chrome://settings/content/microphone in the address bar
- Make sure "Sites can ask to use your microphone" is selected (not "Don't allow")
- Check the "Allowed" list — the site should be here
- If the site is in the "Blocked" list, remove it and reload the page
- Select the correct microphone in the dropdown at the top
Step 3: Allow Microphone in Incognito
If you're using Chrome in Incognito mode:
- By default, extensions and some permissions are blocked in Incognito
- You'll need to grant permission again when the popup appears
- If no popup appears, check chrome://settings/content/microphone

Step 4: Clear Site Data
- Click the 🔒 lock icon → "Site settings"
- Click "Clear data"
- Reload the page — Chrome will prompt for permissions again
Step 5: Check OS-Level Permissions
Your operating system must also allow Chrome to access the mic:
- Windows 11/10: Settings → Privacy → Microphone → Make sure Chrome/Google Chrome is allowed. Full guide
- Mac: System Settings → Privacy & Security → Microphone → Enable Google Chrome. Full guide
Step 6: Reset Chrome Flags
- Type chrome://flags in the address bar
- Click "Reset all" at the top
- Restart Chrome
Step 7: Update or Reinstall Chrome
- Go to chrome://settings/help to check for updates
- If already up to date and still broken, try reinstalling Chrome
- Or test in another browser (Firefox, Edge) to rule out a Chrome-specific issue
