Ah, OK. Then we should revert the commit later.
But let's continue debugging a bit. Could you give alsa-info.sh outputs on both working and non-working states?
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?
Doh, it was the missing stream_pm ops setup. Also I found a few other minor issues. I'm going to submit a fix patch series now.
thanks
