I’ve tried running the same software of ours a Intel NUC. But somehow the audio block is always failing with this error: amixer: Control sysdefault:0 element write error: Operation not permitted. This confuses me specifically because the same thing works just fine on a generic x86 (GPT) image.
Is there someone that can help me find a solution to this issue?
normal amixer commands work, simply any set commands that writes something fail. But i still don’t know exactly why. I hope somebody is able to help here since the intel nuc image is officially supported.
this is just for reference for any other that might had the same issue. The problem boiled down to two things:
pulseaudio was not started as i didn’t had my X server volume linked in the docker compose file
i had to create a custom block with the init_audio_hardware function removed, since it was trying to set something on a card that didn’t exist which lead to a infinite restart loop
