[Freeswitch-users] Intermittent audio issue with Chrome 40-42 and WebRTC

[Oleg Stolyar]

Hi Anthony,

Not sure if it will help but I am able to consistently reproduce this
problem on a Toshiba chromebook.  It happens with 41, 42 and 43 builds and
multiple reboots did not solve it.

If you need a way to reproduce the problem I'll be happy to ship this
chromebook to you to keep.
