I thought it might be the port issue so I tried to switch LMS’s port around…9000,9001,9002…tried quite a few. Couldn’t see still. Anyone know what port Squeezelite on Volumio uses? And is it possible to manipulate the port?
I ran into this same issue, exactly as you describe it.
For me, I was using a RasPi 3b+ with latest volumio installed directly on the disk.
My desired output was through the 1/8" audio jack, using the native squeezelite plugin.
After brute forcing the settings, I was finally able to get it working by changing the following:
Settings>Plugins>Installed Plugins>Squeezelite Player>Settings>Configure Audio Output Settings>Output Device:
Changed the option to: [(default) bcm2835 ALSA] Default Audio Device
^ Note: this is the second option from the top on my RasPi.
Once I saved, and possibly restarted the Pi, it showed up in my LMS docker container.
For reference, these are the ports I am using. Since I also played with changing the ports, I am not positive these are the defaults. But they certainly work for me:
3483
9000
9090
I have searched everywhere for this, even posting in the Gitter chat, without success.
So if this helps you or someone else out, outstanding. It was worth registering for.
I had high hopes after trying your suggestions and it worked the first time, but after changing the name from Volumio to a more descriptive name (have multiple instances and need to be able to differentiate) LMS is no longer finding them. I tried many restarts of the containers (unraid), the pi(s), and still no players show up. I’m hoping I can get this working and replace my Roon setup (mostly for cost, Roon is quite a lovely service but pricey).
