1212081 - getUserMedia doesn't work for audio

Status: RESOLVED WORKSFORME

(Core :: WebRTC, defect)

Description

[Matthias Schertler]

Attachment: test.html

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20150929144111

Steps to reproduce:

I was using getUserMedia with options { audio: true } in Firefox 41.0.1. See attached test.html for my example code.


Actual results:

The browser didn't ask for permission. No success callback, no error callback.

When I close the browser and open it again it says that firefox is already running.

I have the same effect on all pages that use getUserMedia using audio. Video works.


Expected results:

The browser should ask for permission to allocate the microphone. Afterwards the success or the error callback should be called.

Works for me in FF 44 Nightly Linux, and in FF 39, 39.0.3, and 41.0.1 on Windows 7 (with USB headset).

Can someone in QA or elsewhere try this on a Win10 machine?  This may well be a problem with a specific audio device driver under win10 (i.e. not really our bug, though we might be able to work around it).

You could capture logs using NSPR_LOG_MODULES=getusermedia:4,mediamanager:4 (see https://wiki.mozilla.org/Media/WebRTC/Logging) and upload them here.

Reporter, can you indicate what the HW and driver is?  And if possible, get the NSPR logs per above.

I just tried on Windows 10 with Fx 42.0b8 and I get the permission prompt which asks for the microphone access. It worked with the attached test page as well as with our webrtc-landing pages. So seems to be a machine specific problem.
