The CBC in its infinite wisdom has seen to changing their stream URL addresses as of August 25, 2016. Since I listen using a Logitech Squeezebox and a Grace Digital Primo, I was fortunate to find this page, where anyone who cares can add a CBC Radio stream from the interwebs:
With the Primo, log in and go to the My Streams page. Add the stream(s) of your choice. Unplug the radio for a reset, plug it back in, and your stream will be located in My Stuff / My Streams.
I’m currently in discussions with Grace Digital/ECOXGEAR about adding the streams. It appears they may be geographically restricted, as in, if you don’t have a Canadian IP, you’re out of luck. If that’s the case, you might try TunnelBear, a free vpn.
The Logitech Squeezebox appears to have already installed the new streams.
