Getting Unwanted background sound in CROSS BROWSER when we are subscribing stream from
Microsoft Edge (v 15.15063).

Steps to reproduce the issue:
Create the conference and start it from chrome/firefox, let one of the attendee join conference from
EDGE.

Description of the results received:
After stream subscribed event from EDGE we are getting unwanted background sound (like tick-tick)
to every one in the conference.

Additional information:
We are getting this issue as consistent, Even though all streams are in mute everyone in conference
hearing this unwanted background sound.
Note: Sound is coming from the system speaker.
