Hifiberry DAC2 HD not recognized in balenasound in raspberrypi2

Hello,
I am using balenasound with a raspberry pi 2 and Hifiberry DAC2 HD.
Host: balenaOS 2.48.0+rev1 (production)
Supervisor version: 10.8.0

The project has been created with the button “Deploy with Balena”.
I have added BALENA_HOST_CONFIG_dtoverlay=hifiberry-dacplushd for the device (custom configuration variables) but it is not recognized. When I connect to the audio container, I get the following:
bash-5.0# aplay -l
**** List of PLAYBACK Hardware Devices ****

When I use HifiBerryOS, the DAC is recognized though.

Could you please help me?
Thanks.

Hi @atm, welcome to the Forums. Looking at the balenaOS version and Supervisor versions, which are a bit old, was this device previously running balenaSound without the DAC? If so, did it work?

Or, if this is a new build, then I am wondering if you can try version 2.80.5 of the OS (available from the drop-down menu) when adding a new device in balenaCloud. Flash that to SD Card, boot, wait for the containers to download, and see if that works with the DAC.

Hello,
Indeed, balenaSound works fine without the DAC.

I see that 2.80.5 is available only for rapsberrypi4. For raspberrypi2, the latest available in the dropdown is 2.48.0, so I guess I can’t test 2.80.5.

Thanks.

Sorry for the delayed reply on this one @atm … I missed the fact that you were using a Pi 2, so you are correct, version 2.48 is the latest. I will ping the OS team to see if we could actually build and release a newer version for the Pi 2. However, in the meantime, with the DAC installed, can you navigate to http://:3000/support and paste the logs here, so we can have a look? Thanks!

Hello,
