Microphone Audio Dropped on Chrome on Mac


In a Vonage Video API session over the Chrome browser on Mac devices, participants receive no audio from Chrome clients, with no logs or errors being generated. The publisher is able to attain microphone access, but the browser does not receive callbacks with audio data.

  1. Ensure you are on the latest version of Chrome.
  2. Ensure you are using the latest Video API version.
  3. Restart your browser.


This was due to a bug specific to Chrome, hat caused audio bitrate during a session to fall to zero. This bug has been resolved. Within the Video API itself, we have exposed functionality that can be used to detect when this error occurs.
