1518106 - WebRTC microphone input not working (regression)

Status: RESOLVED FIXED

(Core :: WebRTC: Audio/Video, defect, P3)

Description

[Alex Chronopoulos [:achronop]]

+++ This bug was initially created as a clone of Bug #1418694 +++

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171115192300

Steps to reproduce:

- Visit https://test.webrtc.org/
- Allow access to the microphone
- Start the test
- Allow access to the microphone again


Actual results:

On Android, and my OpenSUSE laptop, everything works fine.
On my Gentoo-machine, the microphone check fails.

I can see, that firefox is not opening a capture stream at pulseaudio.
The log of pulseaudio reveals, that a "WebRTC VoiceEngine" connects, but directly looses connection again.
Same problem with a clear profile and settings folder.

- Downloaded binary of 52(ESR) - works
- Downloaded binary of 55.0 - works
- Downloaded binary of 56.0.2 - works
- Downloaded binary of 57.0 - doesn't work
- Downloaded binary of 59 nightly - doesn't work


Expected results:

Firefox properly opens a capture stream at the pulseaudio server, and the microphone check succeeds.
