No sound to Ropieee XL via Squeezelite

Everything looks okay in software, but no sound output - even though LMS is “playing”. I do get sound sent from the same server to an actual HW SB Touch, so the server side works. I also get sound when using the same RPi as a Roon endpoint.
I also tried a different LMS server (without a Roon server installed) and also got no sound.
I have checked that Squeezelite is defined in the Ropieee device with the proper soundcard/out.
There must some definition somewhere I’m missing.
