Steps to reproduce

  1. Burn fresh image DietPi_RPi-ARMv8-Bookworm.img.xz to a sd card
  2. Let it update it self and use the minimal image config.
  3. Install via dietpi-config alsa and change sound output to HDMI.
  4. Install mpg123 and mpv via apt, sound works then rebooted.
  5. Install chromium via dietpi-software and make all the autostart config, test the sound and it doesn’t work prints an error present at the “Actual behaviour”.

Expected behaviour

  • Play sound via HDMI

@MichaIng can you have a look pls

  1. Install mpg123 and mpv via apt, sound works then rebooted.

Did audio output also work after reboot, before installing Chromium? The reboot (changed boot configuration) is much more likely to cause the issue than the Chromium installation.

After the reboot without the the installation of chromium it worked. I did output sound from HDMI.
Thank you

Strange. Chromium on RPi pulls only internal FFmpeg A/V libraries which should not affect other programs.

But ah, the Chromium installation forcefully enables KMS and hence the KMS HDMI driver while the SoC diver is disabled.

Can you try to enable the auto-conversion plugin in dietpi-config audio options? Both drivers natively support different audio formats.
