exaile and rythmbox will not play after playing video from browser (and vice versa)

[eudemonis]

I've been living with the following problem... Whenever I play a video from some website (like democracynow for example) then all my media players like exaile or rythmbox will not play any songs (I press play and nothing happens)... until I restart my browser, then everything comes back to normal... this also works in the opposite way if I play exaile or rythmbox then if I try to play any video from a website the video will not have any sound coming (the video will play but no sound)... any ideas? I've been living with this for couple months now but it's getting a bit annoying...

Same problem here. Very irritating.
Terminal says

Rhythmbox-Message: Missing plugin: gstreamer|0.10|rhythmbox-metadata|Décodeur application/smil|decoder-application/smil
impossible de trouver une application
Rhythmbox-Message: No installation candidate for missing plugins found.

I installed a lot of gstreamer-plugins, still no luck
