balenaSound RPI 3B+ no aux audio

Project help

The onboard jack doesn’t seem to be putting out audio. I tested with hdmi as well and same thing. It seems to be a software related issue.

Here’s the Spotify request error:

Hi, did you make any changes to the code or is it the base version?

4

Also, what OS version are you using?

6

It’s the base version of : balenaOS 2.46.1+rev1 in production mode

10

@gh_loganprieto32 is that 64 or 32 bit?

11

I’m running 64 bit, it’s a Raspberry Pi 3 Model B+ so it should support x64

Hi there, yes, you are correct that the Raspberry Pi3B+ does indeed support 64-bit OS’es, however, the balenaSound project currently does not work on the Pi3 64-bit. You will need to actually revert to a 32-bit version of the OS, and in that scenario balenaSound does work as intended. We have a GitHub issue opened where we will attempt to resolve the issue, that you can follow here: https://github.com/balenalabs/balena-sound/issues/82. Thanks!
