Chromecast No Audio For You!

As expected, the Chromecast Audio Experiment finished without success...

Was sort of expecting that for Linux, even tho I'm running Chrome, but what a hell... Chrome "syncs" ok with the Chromecast Audio, but nothing happens, sometimes it even crashes the whole Chrome (not only the synced tab).

But, I was more optimistic when it comes to casting from a Chromebook... I thought that the thing being an official Google lappie, running on its own Chrome browser... You know the drill, thing might be smoother...
Anyway, exactly the same problem, it syncs ok, but it doesn't reproduce any music at all (strangely you can hear the volume indicator pip when you scale the volume up or down, but nothing else.)
