--- Comment #11 from youenn fablet <youennf at gmail.com> ---
I wrote these two jsfiddles:
https://jsfiddle.net/4so0e2zj/
https://jsfiddle.net/nswj1eLh/

First one allows to start/stop getUserMedia while playing web audio.
The second one allows to start/stop getUserMedia while playing audio coming from PC (source being web audio though).

The level of audio is changing when doing some manipulations like:
1. start playing web audio
2. start capturing audio
3. end capturing audio
4. end playing web audio
5. start playing web audio

At that point, the audio level is lower in step 5 than in step 1.

I am not able to reproduce audio level changes without getUserMedia calls though.
The initial description of the bug does not induce using getUserMedia for audio capture.
@MarkusM, can you clarify whether your web page is using getUserMedia?
