Yeah, i initially wondered about that, but it didn't when i first tried - the app then went a bit laggy so it was kind of hard to see what was working. I have restarted the app and that is now working. GREAT

There is still some odd behaviour though around the mute button...

* UI says it is muted, but music is playing & has volume -
* unmute and music then mutes and will not return.
* Try to unmute via a touch and after a second it UI reverts to muted...
* Go to Web Interface - volume has been minimised
* Use volume keys to increase volume...

I can reproduce.. not a major obviously, but something to look at
