'canRequestAudioTrack' is never returned on Mac or it is FALSY

Reported by matt.ho...@heypinch.com, May 18 2018

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:59.0) Gecko/20100101 Firefox/59.0

Steps to reproduce the problem:
Must do on a MacOSX computer:
1. Capture user media with chrome.desktopCapture
2. Set options to capture desktop audio and video
3. Record video/audio
4. Save and playback audio/video
5. There will be no audio

What is the expected behavior?
I expect to be able to record audio with chrome.desktopCapture.

What went wrong?
"canRequestAudioTrack" is never returned on Mac. Either it is always FALSY or never returned. This happens only on Mac. Windows is working fine. I am using this API: developer.chrome.com/extensions/desktopCapture

Did this work before? No 

Does this work in other browsers? N/A

Chrome version: 66.0.3359.139  Channel: stable
OS Version: OS X 10.13
Flash Version:

matt.hough@ Thanks for the issue.

Tested this issue on Mac OS 10.13.3 and Windows 10 on the reported version 66.0.3359.139 and the latest Canary 68.0.3438.0  by following the below steps.

1. Launched Chrome and downloaded the chrome.desktopCapture extension from Github site.
2. Added the extension to chrome, but cannot see it enable and cant access the options as well.
Attached is the screen cast for reference.

Request you to check and confirm if anything is missed from our end in triaging the issue.

Also request you to provide a sample extension where this issue can be reproduced, which will help in further triaging of the issue.

Thanks..

@susan.boorgula When I said chrome.desktopCapture I meant the chrome API found here: https://developer.chrome.com/extensions/desktopCapture.

A sample extension can be found here: https://chrome.google.com/webstore/detail/recordrtc/ndcljioonkecdnaaihodjgiliohngojp?hl=en. Click on the 'full screen + speakers' option.

When you play back the video after recording, no sound will have been captured.

Similar code for this feature should be found here https://github.com/muaz-khan/Chrome-Extensions/tree/master/desktopCapture.

OSX doesn't support capture of desktop audio, so this is WAI afaik.
