Just running hda-emu with a realtek codec, e g
codecs/canonical/alc292-dell-latitude-e5440-ccert-201307-13941 turns all
nodes, including the internal speaker, into D3. And running a playback
test does not switch things into D0 - even the DAC node remains in D3
even though you try to stream to it, which seems a bit strange.

Could you explain how this is supposed to work?
