Seems like a non chrome issue.

diego.rubio@ do you have any issue with chrome?

Hello ligim...,

It is my understanding that Cordova uses the Android WebView component based on the Chromium project.

On iOS it works fine(with iosRTC), which makes me believe it has to do something with the WebRTC implementation on Android.

Also reported this on SIP.js(https://github.com/onsip/SIP.js/issues/447) and they told me that was something related to the WebRTC libraries. I don't have anything between SIP.js and the Webview.

On the browser can't test that behavior because I have only one audio output on my computer.

I have attached an image with the navigator object output from remote debugging with chrome, that shows some information about versions, don't know how valid they are tho.

Bests,
Diego.

diego.rubio@: Can you provide more specific reproduction steps?
Otherwise this is not actionable by us.

Hello guidou,

Here is a bare-bones project I created on Android Studio, using WebView. You can run it on your device and it should connect to our testing server and start to play the Tetris song.

https://drive.google.com/a/novotorium.com/file/d/0BypXRi9SlpzsLVpnVWJiR1duN00/view?usp=sharing ~23MB

1.- Sound will start playing on the speaker.
2.- Connect Headphones. (sound comes from headphones as expected)
3.- Disconnect Headphones. (no sound from speaker/earpiece)

If you reconnect the headphones, you can still hear the sound there. If you disconnected the headphones and receive a notification that makes a sound, audio will recover to the speaker.

Bests,
Diego.

Can you provide a reproduction consisting in a web page that we can open with chrome/webview?

Sure,

The project already includes the HTML and the setup for permissions. I opened the permissions a bit more so you can download it.

Another Engineer tested it on Android 5.1 and it worked fine there with no audio issue.

I also have attached the bare HTML in this reply.

This is unfortunately not actionable.
From the report, the failure is within a relatively large system, of which Android WebView is just one of many components. The provided JavaScript apparently requires a specific android application and does not even use Web Platform APIs directly but through a library.
Closing this as WontFix. Feel free to reopen once you are able to isolate the failure in a way that can be more directly tested in Chrome or WebView.
