The problem

On various intel devices (hp elitedesk, dell laptop) using intel 8gen cpu and hdmi connection does not want to output audio over hdmi.

Frustration: maximum

The fix

create the path and file # ~/.config/wireplumber/wireplumber.conf.d/force-s16.conf

and set the content

monitor.alsa.rules = [
  {
    matches = [ { node.name = "~alsa_output.pci-0000_00_1f.*" } ]
    actions = { update-props = { audio.format = S16LE } }
  }
]
