• Searched the bugtracker for similar issues including closed ones
• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser

What is the purpose of your issue?

Strictly speaking, NRK Radio is already well supported. This URL is special as it is a (possibly new) podcast-only program.

(I suggest to rename this issue to "Support for NRK Radio podcasts", and make it a site request.)

I assume it uses the identical hosting to the other programs, so an adaptation of the NRKRadio extractor to support this URL might be sufficient. I haven't checked myself though.

(Forresten, elsker Ulrikkes podkast!)
