It was set to hw:0 so I changed it to hw:1. Even with a “Save” it didn’t work until I rebooted. I think it should be made clear somewhere that rebooting is necessary after making changes on the MPD page.
Re: “adding the file linking the station to the MPD folder” — can you give me more of a step-by-step for that? Firstly what file? where do I get it? Secondly what MPD folder, and how do I access it? (Is this in the GUI or by Putty?)
Perhaps an example would help: I want to add this radio station — https://kpfa.org/
Thanks for the additional info.
