I've tested it on one device and it works fine, no clicks.

OK, applied now.
Alsa-info for this device is available here: https://launchpadlibrarian.net/228090406/AlsaInfo.txt
Possibly it works well for other chips too, but this is the only one I have tested.
Btw; I noticed another thing which I wonder whether it's correct or not: If I run "hda-emu AlsaInfo.txt", all nodes are in D3. But after running "P 0 p", some nodes (e g the internal speaker pin) stays in D0. Is that expected?
Yes.
I thought all pins would go down to D3 when playback closes. Same behaviour is seen on the real hardware, too.
It's for sticky converter. There was an issue where powering up/down there triggers the click noise. So we keep the converter and the rest on as default once when assigned and used.
This can be likely optimized out with the modern chips, I suppose.
thanks,
Takashi
