HDMI audio not working

[imp1sh]

When I choose HDMI audio output during installation wizard it won't work. The Tidal App seems to be connected but the track just isn't playing, it's stuck at the given time.

This is an excerpt from the logs:

This is the config file:

FRIENDLY_NAME=raspberrypi
MODEL_NAME=raspberrypi
MQA_PASSTHROUGH=false
MQA_CODEC=false
PLAYBACK_DEVICE=vc4-hdmi: MAI PCM i2s-hifi-0 (hw:1,0)

Is it possible that HDMI audio output just isn't possible? This is not hifiberry OS but Raspbian 11.3 on a Raspberry Pi 2 Model B.

Do you get any other Audio via HDMI working? On Hifiberry this is not possible (not supported by OS).

This is tragic. Doesn't HDMI mean High Definition Media Interface?

I think there is a way via the ALSA mixer to sort this out. You could try "default" or "sysdedefault" from installation menu. Ofcourse we need to make sure that Audio over HDMI is working as expected if its not. On RaspianOS this is done using raspi-config->General->audio. Alternatively Instead of running the process througb docker (which would require you to passthrough your HDMI device, you can also try and run the binary directly on RaspbianOS. Have a look at the entrypount.sh script for the command line options.

I have some time this week and get testing with Raspbian + HDMI audio. Hope this can be fixed.
