Audio issue: Microphone not working, other participants can't hear me

Other participants not being able to hear you can be due to several reasons. It's either

  • Your microphone is not working; or
  • Their speakers are not working

First, run pre-call test on your device to make sure your microphone is set up and working. 


Here are a few things to try:

Refresh your browsers

Sometimes your browser doesn't connect to your microphone or their speakers properly. Have both you and your participants both restart your browsers to give them another chance to connect properly. 

Are their speakers turned on?

Make sure your participants can hear sound from their speakers. If they have headphones or other speakers connected, make sure the sound isn't playing there. To confirm that sound is working, have them play this video.

Are the correct microphone and speakers selected? 

Open Blitzz device settings before or during a call to check which speakers and microphone are used. Both you and your patient need to check this. 

Do you have a microphone?

Your computer may not have a microphone, or it's not plugged in or turned on. Check to make sure you have a working microphone?

Is your microphone muted?

If you have a microphone with a press-to-mute button, make sure it isn't muted. Also, Blitzz has its own mute button, make sure you don't have it on. 

Did you give permission to access your microphone?

The first time you log into Blitzz, your browser will request permission to access your microphone. If you denied access, they won't hear you. Reset the permissions.

Restart both your computers <-- THIS SOLVES MOST ISSUES

Sometimes other video conference software (e.g. Skype, Teams, Facetime) can block access to your microphone or speakers. Restart both of your computers, then try again.

Is your browser up to date?

Out of date browsers can cause audio issues, make sure your browser is on the latest version

Check your computer settings

Your computer settings may prevent you from sharing your microphone.  Check your microphone computer settings on Windows or Mac. 

Switch Browsers

Sometimes there can be an error on your browser. Try using a different browser to see if it works. Blitzz is compatible on Chrome, Firefox, Edge, & Safari.

Check antivirus, firewall, or parental settings

You may have antivirus, firewall, or parental control software installed that is blocking access to your microphone. 

Update Camera and Mic Drivers

Update webcam with Device Manager / Lenovo Vantage or Logi Capture
