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 Previously reported at: https://github.com/tiliado/nuvolaplayer/issues/85 https://bugzilla.gnome.org/show_bug.cgi?id=746913
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.
