Unable to hear participants voice when automatically recording has started

Working with Openvidu, I am facing an issue with participants voice as we are not able to hear eachothers voice when recording automatically started with even one participant in the session, However when we make the startrecording api call manually with a click event after participants join the session , then we are able to hear voices.I am integrating this in an Android application(JAVA), I tried enabling device audio source also.

Here is the difference that i found when there is no voice streaming but participants connected in the session.Please check the screenshot

Found the same issue in he Demo application as well.
