Sorry your having such a hard time with this. I can’t figure out why there is no error messages. Have you tried viewing the logs directly? I mean look at the actual log file itself. I think looking at the log from HA, you will only see a message if something actually triggers an error. I’m just wondering if there might be some logging going on that for whatever reason is just not being treated like an error (which means you don’t see it in HA)
And this is my first custom component. And it’s really more of a hack and expand job on the original gmusic_switch. There are some people using this with no issue but it’s still just as possible that your problem is caused by my lack of real programming skills. Gmusic Player can also stream from a locally running gmusicproxy but that is a workaround for skipping tracks. gproxy should not be required for the music player to function.
If you’re just troubleshooting, you can give Chromecast Radio a try. It’s basically the same thing, just different – Seriously it uses to same methods to start playback on a device, it’s just playing web radio-streams. I don’t really know anything about the stream (if there restricted to certain areas) but I grabbed the first one from the list.
Might even be able to just try a one off example to check on Kodi.
