Audio Failures on Chrome 66 Due to Autoplay Policy


When using Vonage Video API over Chrome 66, interface sounds do not play, the audio visualizer failures, or your WebRTC application does not play sound from remote peers. The audioLevelUpdated event and the animation for audio level do not work.

This issue is related to Chrome's autoplay policy, which was introduced with Chrome 66.
