If I play a radio station through the BBC website, e.g. (I believe this is available worldwide): http://www.bbc.co.uk/radio/player/bbc_radio_two
When I mute the mac the playback pauses. This doesn't seem to be a feature of the website and has started since updating to Yosemite (10.10).
Sounds pretty cool (like I say, doesn't seem to be something offered by the BBC) however I'm using this as a Alarm Clock, so load the webpage automatically a bit earlier than its needed and fade the sound in - now all the time checks are out (more than usual)!
Any ideas why this is happening and if anything can be done to turn it off.
