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? -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic
