Bug 144773 – [GTK] Volume drops on performing any action in chrome while playing {youtube, google play music} in another WebkitGTK based browser

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKitGTK

[Vishal Verma]

System info:

Fedora 21 with gnome-shell 3.14.3, and epiphany 3.14.2, with google-chrome Version 39.0.2171.95 (64-bit).
webkitgtk4.x86_64  2.6.6-1.fc21

I've seen this happen with both the Epiphany browser, and nuvolaplayer (a WebkitGTK music player for web based music services).

Steps to reproduce:
1. Open Google play music or Youtube, and play a song or video
2. Switch to google-chrome
3. Refresh any tab in chrome (new-tab page is OK too)
4. Volume of media being played in Epiphany drops by about 50%
    - Neither the system volume bar nor the volume bars in the web apps change position
5 - After about 15-20 seconds, volume is restored

How reproducible: Always

Chrome Plugins:
Chrome PDF Viewer
Chrome Remote Desktop Viewer
Native Client
Widevine Content Decryption Module - Version: 1.4.6.703
Google Talk
Google Talk Plugin Video Renderer
Adobe Flash Player - Version: 16.0.0.235

Seems like yet another PulseAudio issue?

Not sure to see how this could be a WebKitGTK bug. We're playing some media in Epiphany and all of a sudden an action in Google Chrome triggers a volume level drop?

I looked into this again to retest with different combinations of browsers, and I can't reproduce the original issue any more..

Either a recent update (my original bug against nuvola player is over a month old..) fixed it, or it was something transient.

Anyway, until I can reproduce it again, we can close this.
