Steps to reproduce the problem:
1.Enable native simulcast
2.Start Conference 
3.Jitter Buffer and Current Delay increases suddenly. It is up to 2500 ms
4.Change the simulcast type to Simple Simulcast which basically gets two streams with webkitGetUserMedia. One for low quality, one for high quality.
5.Refresh the session.
6.Jitter Buffer and Current Delay is around 150 ms which is not disturbing

Codec is VP8.

What is the expected behavior?
Not to have lipsync problem

What went wrong?
lipsync problem

Did this work before? N/A 

Does this work in other browsers? N/A

Chrome version: 56.0.2924.76  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 24.0 r0

As far as I understood from the below discussion, jitter buffer should not be increased this much,

"
> How does Chrome handles clock drift between the sender and the receiver? 

This is handled by the jitter buffers and associated time-warping done 
to avoid jitter buffer buildup.  Basically, the mechanisms for an 
adaptive jitter buffer as a side-effect will compensate for clock drift 
between sender and receiver.
