Does Live Web Audio Input work in Google Chrome on Ubuntu?

Question

According to this article the following code should work on OSX and Windows but doesn't mention Linux:

http://updates.html5rocks.com/2012/09/Live-Web-Audio-Input-Enabled

// success callback when requesting audio input stream
function gotStream(stream) {
    var audioContext = new webkitAudioContext();

    // Create an AudioNode from the stream.
    var mediaStreamSource = audioContext.createMediaStreamSource( stream );

    // Connect it to the destination to hear yourself (or any other node for processing!)
    mediaStreamSource.connect( audioContext.destination );
}

navigator.webkitGetUserMedia( {audio:true}, gotStream );

I downloaded Chrome Dev which is version: Version 25.0.1323.1 dev and it's not working.

I have the following flag enabled:

Web Audio Input Mac, Windows, Linux, Chrome OS
Enables live audio input using getUserMedia() and the Web Audio API.

Answer 1

Linux support for live audio was added in https://src.chromium.org/viewvc/chrome?revision=192893&view=revision.

Currently works on Google Chrome Version 28.0.1500.89 beta. Tested on Arch Linux.

Answer 2

As of chrome Version 24.0.1312.69 and Dartium Version 26.0.1403.0 (chromium derivative), I could not manage to make any demo from http://webaudiodemos.appspot.com/ using Live Input work on Ubuntu 12.10. I have the proper chrome://flags enabled.

For me it works fine on MacOS but it fails on Ubuntu using either a microphone or a USB camera. Ubuntu Sound Recorder works fine though so I know my hardware is working.

It would be nice to know whether it is supposed to work on Linux or when it is planned to be officially supported.

I can verify this as well. Created ticket on the official Chromium bug tracker:
