Bug 256803 – [GStreamer] Wrong icon (loudspeaker / speakerphone) shown in browser tabs playing silent or muted looping videos

• Status: NEW
• Component: Media

With Epiphany 44.2 + WebKitGTK 2.40.1 + GStreamer 1.22.2, as packaged by Fedora 38, if you visit https://interbrand.com for example, it will autoplay a muted version of a looping video in the hero banner area at the top. There is an unmute button you can click on the video, but let's not care about that for now.

The problem is that even if it's playing silently, it shows this loudspeaker icon in the tab in the Epiphany UI (and sometimes it bugs out and even shows it when the tab is unfocused, whereas at other times it does not show it): https://gitlab.gnome.org/GNOME/epiphany/uploads/e4f07aa1b9d7e431b1df35d7c6001263/image.png

Shouldn't it use a different icon (or no icon at all) when the playing videos are muted or have no audio track?

MiniBrowser works fine here: https://cloud.igalia.com/s/oTxB9e3ny7bod28

Is this a flaky behaviour?

I was able to reproduce the bug in MiniBrowser on the first try. The WebKitWebView:is-playing-audio property must be set incorrectly.
