Allo Digione - untested audio interface not working

I wanted to use balenaSound for my RPB3+ and my Allo DigiOne audio transport. I inserted a custom configuration variable named “BALENA_HOST_CONFIG_dtoverlay” with the variable “allo-piano-dac-plus-pcm512x-audio” as per the instructions for the untested audio interface GitHub list but audio doesn’t play.
Even when changing volume both in Spotify, airplay and the master volume nothing changes and the receiver tells me that no signal is traveling into that input.

Hi Eric, two quick questions on this. First, what version of balenaOS are you using? You can find out in the balenaCloud dashboard, or, simply check the filename of the SD Card image that you downloaded.

Second, can you browse to https://<DEVICE_IP>:3000/support and provide the logs to us, so we can have a look?


Hi, I am running the production version of BalenaOS 2.80.1 + rev1. I hope these are the right logs. It is important to note that “joining the fleet” can take up to an hour or doesn’t happen at all. But the scenario I described above refers to one where it eventually does connect to the fleet and shows up in Spotify connect and airplay.

Hey @ktz228, catching up with this thread, were you able to figure this one out? From the logs you shared it seems the multiroom services are erroring out. I would try restarting them through the dashboard. If you are not using multiroom then you can disable it by setting SOUND_MODE=STANDALONE, see Customization - Home for details.

Also, what happens if you use the audio port on the Raspberry Pi, does that work? Chances are that the DAC needs some extra configuration to work and we need to figure out what.

Any luck with Tmigone’s suggestion?
