Hifiberry dacplus


I have 3 Raspberry pi’s 4 (64bit) On each PI i have a Hifiberry sound card “Hifiberry-dacplushd” Everything was good for almost 3 years. After doing an update i don’t see my sourdcards anymore.

i try really all variations of settings but noting helps.

Please can anybody help me i read already hours on internet.

balenaOS 2.115.1

I have installed HifiberryOS and that work fine, so the sound card is OK.

Please can anybody help me out?

Hello @arjan5340,

You mentioned version 3.9.6. So I’m assuming that you are running balenaSound.

You mentioned that you don’t see your sound cards anymore. Could you please expand on that e.g. which command(s) did you run and what output did you see? Could you please run this command in the audio service/container and reply with the output: aplay -L. You may have already run that command …

It sounds like you have had this setup for years, but let’s make sure that the BALENA_HOST_CONFIG_dtoverlay variable is still set properly. Should still be set to hifiberry-dacplushd. Is that still set? See Audio interfaces | Balena Sound.

Also, you mentioned that the problem appeared after an update. Was that a balenaSound application update or a balenaOS update?
