iTunes Radio Won't Play Music
iTunes Radio on my Mac Mini won't play. The songs load up, but no music is played and the progress bar always stays blue (i.e., doesn't show up like a normal song playing where it starts at the beginning and as the song progresses moves towards the end). If I skip a song, it makes no difference. The new song loads up on the player but it doesn't play and the progress bar remains blue all across.
This has been acting up off and on, but it usually would get working after I'd quite iTunes. It started acting up again yesterday and I was unable to get it to play. I then upgraded to Yosemite 10.10.3 overnight and today I upgraded iTunes to 12.1.2
I've signed in and out of my account, reauthorized and reauthorized the computer, signed in and out of iTunes Match to no avail. This only happens on my Mac Mini. I have no problem playing iTunes Radio music on my iMac, iPhone, iPad, etc.
Any suggestions? I have tried just about everything I could think of.
Best regards, Phil
