This guide helps you resolve audio issues (microphone and speakers) with kMeet, Infomaniak's ethical video conferencing solution.

Preamble

• For kMeet to function, it must obtain your permission to access the microphone.
  • This request usually appears via a pop-up window in the top left of your browser or when you first launch the application.
• An audio issue can be of two types:
  • either others cannot hear you (microphone issue),
  • or you cannot hear others (speaker/output issue).

Steps to resolve an audio issue

1. Check the hardware and basic settings

1. Mute button: check that your microphone is not muted in the kMeet interface (red microphone icon) or via a physical button on your headset/microphone:
   
2. Connections: if you are using a headset or an external microphone, unplug it and plug it back in (prefer direct USB ports over hubs).
3. System volume: check that the volume of your computer or mobile device is not set to zero or in "Do Not Disturb" mode.

2. Configure audio settings in kMeet (Computer)

Whether on the application or the browser, you can precisely choose your devices:

1. Access the Settings:
   
2. Go to the Audio tab:
   
3. Microphone: select the correct device from the list.
   1. Speak: a blue volume bar should move if the microphone picks up sound.
4. Audio output: select your speakers or headset.
   1. Click on "Test" to check that you hear the test sound.

3. (Re)authorize the microphone in the web browser

If you are using kMeet via Chrome, Firefox, Safari, or Edge:

• 
• Click on the lock icon (or site settings) to the left of the URL address (kmeet.infomaniak.com).
• Check that "Microphone" is set to Allow.
• If you change this setting but with no noticeable effect, refresh the page (F5).

4. Check system permissions (Windows, macOS, Mobile)

On macOS (often forgotten):

1. Go to the Apple menu > System Settings > Privacy and Security.
2. Click on Microphone.
3. Check that your browser (Chrome, Firefox) or the kMeet app is checked.

On Windows:

1. Go to Settings > Privacy and Security > Microphone.
2. Check that the "Microphone access" option is enabled.
3. Check that "Allow desktop apps to access your microphone" is also enabled for kMeet or your browser.

On Mobile (iOS and Android):

• iOS: Settings > kMeet > Check that Microphone is enabled. Also check in Settings > Privacy > Microphone.
• Android: Settings > Apps > kMeet > Permissions > Microphone > Allow while using the app.

5. Special case: Disable blocking extensions

Some browser extensions (AdBlockers, privacy protection extensions like uBlock Origin or Privacy Badger) can sometimes block audio/video streams.

• Try disabling your extensions or opening the kMeet link in a private browsing window to test.

6. About Firefox and WebRTC

You can try disabling WebRTC in Firefox to test (via media.peerconnection.enabled = false) but this is not recommended: kMeet uses WebRTC technology to function; if you disable it, the video conference may no longer work at all.

If Firefox is causing issues:

1. Check in Firefox settings > Privacy & Security > Permissions.
2. Next to 'Microphone', click on Settings and make sure that kmeet.infomaniak.com is not in the 'Block' list.
3. Also, check that Autoplay is allowed for audio on kMeet.

7. As a last resort: Switch devices

If the problem persists, it is likely a hardware failure or a driver conflict on the device:

• Join the meeting from another device (switch from computer to smartphone via the kMeet app).
• Get the meeting link/code via shares/invitation:
