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 errors, WebRTC 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.
