Won't Play Certain Audio Streams

Loaded PiMusicBox into my Raspi 3 B+ so I could listen to internet talk radio streams. Streams such as NPR, WAMU, and WQED play fine, but some streams won’t play at all. They will play through iTunes or on a MacBook but won’t play through PiMusicBox - for example:

Any idea why these won’t play - is a specific codec or Mopidy extension needed? I’ve experimented with different suffixes of the urls but no success so far.

Thank you!

Found the cause - all working fine now. Thanks for all of your help
