Vantact Web Application No Audio Troubleshooting

Step 1: Basic Device/Audio Checks

  • Volume/Speakers: Ensure the laptop isn’t muted and that the correct output device is selected.

  • Test audio in other apps (e.g., YouTube, Zoom, etc.): This confirms it's not a system-wide audio issue.

Step 2: Chrome-Specific Checks

  • Check site permissions:

    • Go to the Vantact web app URL provided

    • Click the lock icon in the address bar.

    • Ensure Microphone and Sound are set to “Allow”.

  • Open Chrome settings → chrome://settings/content/sound:

    • Make sure the site isn’t muted or on the blocked list.

    • Global setting should say "Sites can play sound."

Step 3: Vantact Web App Specific

  • Browser console errors:

    • Press F12 > go to the Console tab.

    • Look for any JavaScript errorsWebRTC failures, or permission denials.

  • Network tab:

    • Check F12 > Network tab when joining a call.

    • Look for blocked STUN/TURN or WebSocket failures.

Step 4: WebRTC/Audio Device Settings

  • In the Vantact app:

    • Go to the Settings or Preferences section if available.

    • Confirm the correct audio output device is selected.

    • Some Vantact builds allow audio testing (check for test call or sound device section).

  • Run chrome://webrtc-internals/:

    • Open this before joining a call.

    • Look for audio track stats and whether audio packets are being received.

    • If packets are being received but no sound, it's likely an output issue.

Step 5: Windows-Specific Checks

  • Sound mixer: Right-click volume icon > "Open Volume Mixer" → Ensure Chrome isn’t muted.

  • Privacy settings:

    • Start > Settings > Privacy > Microphone → Ensure Chrome has access.

    • Even though it’s audio out, misconfigured mic permissions can cause WebRTC issues.

  • Audio output devices:

    • Right-click speaker icon → "Sounds" > Playback tab

    • Try setting a different output device (e.g., internal speakers vs. headset).

Step 6: Reset or Isolate the Issue

  • Clear browser cache or use Incognito mode to rule out bad extensions or cache.

  • Try logging in with a different Windows user account on the same machine.

  • Try using Firefox or Edge to see if it’s Chrome-specific.
