Music playing stack status

I have my credit card ready if and hopefully when Mycroft has a recommended music streaming service. In the meantime I’ve been trying to get song files on a USB drive and Internet radio playing well together. Here’s a summary:

  • Jellyfin no longer appears to be working as a music indexing engine.
  • Falling back to Emby, it seems to be partially working:
    • ‘play $artist’, ‘play $album’ and ‘play $track’ work, but
    • ‘play artist $artist’, ‘play album $album’ and ‘play track $track’ do not - Here’s a snippet from skills.log:

I did see a Python error in audio.log, if that might help:

2022-04-03 14:43:53.095 | ERROR    | 898746 | concurrent.futures | exception calling callback for <Future at 0xffffb092b9a0 state=finished raised AttributeError>

In the file “/home/pi/mycroft-core/mycroft/audio/”, here are lines 385-387:

        def restore_volume():
            LOG.debug('restoring volume')

Hope this helps.

Hi Mike. After reading your post, I thought that I might give this a go, well the skill installed nicely, and Mycroft in her infinite wisdom said she would play streaming from , or something to that affect. But know sound that I can hear, I’ve spent the last hour at lines 376-399, but nothing jumps out. Maybe I’ll have a drink then return to it with a new set of eyes

@Valentine - thanks for the reply.

I just tried streaming Internet radio again. It didn’t work :frowning: So I started Mycroft in debug mode, and then it did work. Go figure.
