see forum topic: Raspberry pi headphone jack no longer works with latest OS

I have just upgraded my device to production balenaOS 2.41.0+rev3 on my raspberry pi and I can no longer play audio through the headphone jack.

The following command lists all alsa playback devices on my raspberry pi.

bash-5.0# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi [vc4-hdmi], device 0: MAI PCM vc4-hdmi-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
bash-5.0#

When I executed the same command on another rapsberry pi 3 running development balenaOS 2.38.0+rev1 I get the following:

I am not specialist but it looks like the raspberry pi audio driver has changed when upgrading the OS and I don't know how I can play now audio through the headphone jack.

As workaround I have moved back to BalenaOs balenaOS 2.38.0+rev1 and that works fine.

upgrading to host OS to version balenaOS 2.43.0+rev1 fixed the issue.

See following output:
