Bugzilla

The setup:
Alice is running Windows 10 insider using Firefox Nightly
Bob is running Windows 10 using Firefox Nightly.

Bob and Alice enter a WebRTC call. Alice can only hear Bob when she is muted, and Bob can only hear Alice when she is unmuted.

When Alice switches to release, everything works as expected.

I can reproduce this using https://appear.in and https://riot.im. I will post a regression range and logs.

The setup:
Alice is running Windows 10 using Firefox Nightly
Bob is running using Firefox Nightly.

Bob and Alice enter a WebRTC call. Alice can only hear Bob when she is **self muted** (strange), and Bob can only hear Alice when she is unmuted (normal).

When Alice switches to release, everything works as expected.
