Echo from Chrome users

Affects

Dolby Product(s)

• Dolby.io IAPI javascript sdk

Third Party Product(s)

• Chromium based browser

Description

Multiple getUserMedia requests causes echo from Chrome users. 

Reproduction Steps

1. Make a getUserMedia request to acquire the microphone.
2. Join conference with audio:true

Workaround(s)

• If your application is making a getUserMedia request outside of the SDK, the audioTrack must be stopped after use and before joining the conference. You can use the MediaStreamTrack.stop() method to achieve this.

Action Plan

• We are investigating overriding device constraints to enable echo cancellation properly.
