POSSIBLE WORKAROUND!!!???
iTunes Radio plays 1-3 songs, then, no audio... Still shows it is playing, but no audio... Restarting, Skipping, nothing helped. I had tried everything... I had Time Warner come out and replace our cable modem, replaced our Apple Airport Router/Time Capsule with a new one (now I have 2), reconfigured our WIFI.... hardwired with GB ethernet.... nothing helped... I know this seems elaborate just for iTunes Radio, but I had some other issues with AirPlay and Apple TV & Netflix and Hulu that I was trying to address also.... Still however while all this helped with those other issues, iTunes Radio still playing without audio after 1-3 songs...
Until this!!! After seeing this post I decided just to try different DNS servers... I switched DNS from Time Warner, then to Google, then to Level3... 209.244.0.3, 209.244.0.4
Level3 DNS seems to have done the trick for me... Been listening to iTunes Radio for 2 Days non-stop without hiccup... thus far . And now I think I might like iTunes Radio as much as Pandora Especially in that my Stations Sync to all my Apple AirPlay enabled devices.... 😎
I look forward to hearing back if others of you are successful or not with this possible solution? Hope this helps.
Here also is a list of DNS servers for anyone wanting to experiment and report on iTunes Radio compatibility with others...
