I guess it doesn't happen -- at least with the legacy HD-audio and the recent chip, if I understand correctly. When the stream is on the analog codec, the HDMI codec is kept closed / runtime-resumed. And the additional get_power() in the controller side is done only for HSW/BDW (where the HDA-bus is dedicated to HDMI).
