Bug#824675: WebKit: System volume gets too loud automatically

Package: libwebkit2gtk-4.0-37
Version: 2.12.2-1
Severity: normal

Each time a new audio or video file is loaded and starts playing, or
each time that their volume is set from inside the browser, the
computer's sound output level gets set to its maximum value. This bug
seems to be inherent to WebKit and not specific to any library using
it, and does not seem to happen with any non-WebKit web browser.

This has been corroborated by testing in GNOME Web, Midori (using the
package libwebkitgtk-1.0-0 version 2.4.11-1) and QupZilla (with
libqt5webkit5 version 5.5.1+dfsg-2+b1); and also in Firefox ESR and
Chromium, where the bug could not be reproduced.

I am using the latest available GNOME desktop (Shell 3.18.1-1) with
ALSA 1.0.27+1 and PulseAudio 8.0-2+b2.

The bug was sent to this buglist because I cannot find or test the
error outside Debian and this package is possibly the most relevant
version of WebKit available on it.
