Since I upgraded to Ubuntu GNOME 15.04 using Firefox and GNOME 3.14 I stopped getting desktop notifications (no visual or sound), although now that I have upgraded to GNOME 3.16 I am getting, delayed, but still the visual built-in notifications. Though still no sound, and every time that I do get pinged I notice this message in my Firefox console log:

So I am wondering why I am getting this, in what, and how to fix it?

This issue may be occurring because there are no packages available to decode the MP3 sound file. They may have been present on your previous installation but lost during the upgrade.

Check to see if you have a package to perform the decoding (such as ubuntu-restricted-extras).

  • Ok, I have tried installing it, and other than causing me lots of trouble, it didn't fix anything... :P –  Sep 25 '15 at 21:06
  • I can see from the linked question that the installation (I am guessing has now been fixed). Does the same error message appear when a notification occurs? – crimsonspectre Sep 28 '15 at 04:49
  • Oh dear, there was I looking at my log trying to see it while people were pinging me getting annoyed at all the noise and how it was distracting me from finding the entry... :P –  Sep 28 '15 at 17:54
  • But on the normal Ubuntu with Unity there is no need to install ubuntu-restricted-extras in order to hear this sound so what package do they use to play it? –  Dec 13 '15 at 19:59
  • It might be that a) Ubuntu doesn't need that package natively but Firefox only uses that package for its MP3 file playing or b) that installing that package "enables" that other native MP3 playing (as it needs to be restricted in other countries) to work for Firefox. – crimsonspectre Dec 16 '15 at 12:21
