Created a new system for balena sound, but the headphone jack is not working.
Tested the speakers and the rpi4 itself with Raspbian, it just seems to be balena.
Cat /proc/asound/cards shows only the HDMI devices for 0 and 1, no bcm or other analog audio.
It is stock flashed out of the box balena with sole purpose of audio streaming.
Some research showed this being an old problem, but the older solutions don’t seem to work. Let me know what you want to see or have me run, happy to change anything to make this work.
Have rebooted many times, and even reinstalled new fresh to be sure, still no audio out of 3.5mm Jack.
First thing would be to look at what version of balenaSound are you running on your device wrt which balenaOS version? Also, it would help to double check the setup instructions here: Getting started - Home
I can suggest a couple of things you can check, and lets see if we find anything which helps resolve our issue here:
Check if you are on 64 bit balenaOS. Ref: Support - Home
Check if you docker-compose.yml has priviledge: true
Just created an account, just started using this. Not exactly a linux noob, but things are not quite where I expect them in this OS. I would assume that a fresh install with nothing else should work out of the box, and have basic item enabled from the start.
Since you are using a 64 bit OS, have you tried removing the vc4-kms-v3d dtoverlay setting from the Device Configuration section of your device?
To check your docker-compose.yml go to the “releases” page for your fleet, (on the left side menu) and click on the current release. The docker-compose.yml file will be on the right. We just want to confirm that the audio service has the entry privileged: true.
