Hi Takashi,
A recent change in sound.git seems to have introduced some repoll after pm. Is this an intentional change? I don't think it's wrong per se (it stops after 6 repolls), but it breaks my hda-emu tester when "list" does not return the expected input.
Hm, there is no such an intended change.
After testing some more, I've found that reverting e90247f9 (Split ELD update code from hdmi_present_sense) fixes the issue, so it seems like this commit indeed contains a functional change...
...notice how the last two lines are somewhat unexpected output for a "list" command, but I can make my tool more robust in case you confirm this is an expected change.
When the list may trigger some runtime PM, the jack status report itself should have been present at resume in earlier version, too. Do you see the repoll there?
To clarify, it's not power up or power down, it's flush_delayed_work that runs after every hda-emu command that causes "list" to also report the jack status.
