Balena audio-block error: "amixer: Control sysdefault:1 element write error: Operation not permitted"

[Orbisti95]

Hi there,
I'm using balena along with balena-browser https://github.com/balena-labs-projects/browser and balena-audio for my app (also using appache and websocket for communication) which is running in kiosk mode. My web app is playing some videos, user hearing the sound via headhones from 3.5mm jack. This setup worked perfectly for months.
I don't know why, maybe some version changed, but now I'm getting an error message from the audio service:
amixer: Control sysdefault:1 element write error: Operation not permitted
and sound is not working on device.

Device has type of Generic x86_64 (GPT).
Adding content of my docker-compose here:

version: '2'

Also getting these logs on balena-cloud:
Its seems audi service is failing and keep trying to restart.

Could anyone help me with this?
I'm read all the sites, tips found on internet. Nothing helped.
