Specs: Chrome version 44,45,46 both Win, Mac and Linux.

Actions made:
1) first source: camera and microphone granted via getUserMedia
2) second source: microphone only granted via getUserMedia
3) both sources are stored in JS object
2) volume level checked with WebAudio (getting peak level over 5 seconds)
3) WebRTC call established within a first source

Symptoms:
1) volume level is detected as 0
2) in the WebRTC call one user doesn't hear the Chrome user

Expected behavior:
1) volume level is detected higher than 0
2) in the WebRTC call both users hear each other

Severity: often, but not always. Doesn't seem to be tied to particular user, it happens from day to day with any user.

Can sometimes be temporary fixed by restarting Chrome completely.

Can sometimes be temporary fixed on Mac (until restart):
1) Go to Mac Applications > Utilities > Terminal
2) Copy and paste this command, then press Enter: sudo killall VDCAssistant
3) Type in your computer password and press Enter
4) Restart Chrome

Does anyone still get the same issue?
