I’m having an issue with balenasound on a raspberrypi 3 all the services are running but in the log I get this over and over

And no sound. Not sure what is wrong, I got it working perfectly on a raspberrypi 4

Hi there,
can you let us know what you have tried ? Are you following a step by step guide ? Have you set any custom environment variables ? have you already tried with the Deploy with balena button ( https://github.com/balenalabs/balena-sound ) method?

This seems to be a problem with snapcast that we use to add multi room support. Looks like you are indeed using that since you have two devices set up. Could you please try to disable multi room support by following these instructions https://sound.balenalabs.io/docs/customizations#disable-multi-room and check if the device work as expected ?
Just for ref: https://sound.balenalabs.io/docs/
