Steps to reproduce:

1. Open a fresh Firefox window
2. Go to https://jsfiddle.net/7jLjgg3d/3
3. Start a recording and stop it after a while.
4. Play the recorded file in the player.

The recorded audio is distorted and slowed down in Firefox 45 (was perfectly fine in Firefox 44) 

Now, if I play one of the audio files from the link in the following bugreport in a new tab: https://bugzilla.mozilla.org/show_bug.cgi?id=1203616, stop the audio files, go back to my tab, and start the recording again, the recorded audio is perfectly fine.


Actual results:

The first time around, the recorded audio is severely distorted.


Expected results:

The audio should have recorded cleanly like it did the second time around, after playing an audio file in a second tab.
I'm able to reproduce in 45, but not in 48, so it has been probably already fixed.
Can you test Nightly to confirm it's fixed: https://nightly.mozilla.org/

I have tested the following versions:

46.0b5 - issue still present
47.0a2 - issue is fixed
48.0a1 - issue is fixed

This is kind of an annoyance, since FF46 is being released soon, but it's still broken in this version, which means my code is useless.

Is there any workaround to temporarily make it work for FF45 - FF46?
