If you’re unable to hear other participants in your Blitzz session, there may be a few possible reasons:
- Their microphone may not be functioning properly
- Your speakers may not be working
- Their microphone permission is disabled
- There may be network issues
To begin troubleshooting, run a pre-call test on your device to ensure your microphone and speakers is correctly set up and working.
Ask the other participant to run a quick test to confirm their speakers are working. You can share this link with them: https://web.blitzz.co/networktest
Here are a few things to try:
Check your audio output and ensure your speakers are turned on.
- Ensure your speakers or headphones are connected and turned on.
- Verify your system volume isn’t muted or set too low.
- If you’re using external speakers or a headset, make sure they’re selected as the output device in your operating system’s sound settings.
- Try playing a test sound outside the video call—such as Play this video, to confirm that your speakers are working.
Ask the Other Participant to Check Their Microphone
- The person you can’t hear should confirm their microphone is connected and not muted.
- They should also make sure the mic is selected correctly in their device’s audio settings or within Blitzz Call Settings.
- Ensure they have a working microphone.
Is your participant's microphone muted?
If your participant has a microphone with a press-to-mute button, make sure it isn't muted. Also, Blitzz has it's own mute button, make sure they don't have it on.
Has your participant granted microphone access at the browser level?
In participant browser: If your participant joining a Blitzz session for the first time, the browser will ask permission to access the microphone. If they previously denied access, you won’t be able to receive their audio. In this case, Ask them to reset permissions.
Restart both your computers *
Sometimes other video programs (e.g. Skype, Facetime) can block access to your microphone or speakers. Restart both of your computers, or close these programs, then try again.
Check if your browser is up to date
Running an outdated browser may result in audio performance issues. Ensure that you are using the latest version of your browser to maintain optimal compatibility and functionality.
Check your participant’s computer settings
Your participant’s system settings may be blocking microphone access. Check their microphone permissions and sound settings on Windows or Mac device to ensure access is enabled.
Check your participant’s antivirus, firewall, or parental control settings
Your participant’s antivirus software, firewall, or parental control settings may be restricting access to their microphone. Ask them to review these settings to ensure microphone permissions are not being blocked.
Update your participant’s camera and microphone drivers
Use Device Manager, Lenovo Vantage, or Logi Capture (for Logitech devices) to ensure your participant’s webcam and microphone drivers are up to date.
