I've originally tested this on TGL and DG2, so can you be more specific

Hm, I somehow believed that patches have been tested by intel people,
as they came from intel.  (Also thought that drm-tip or whatever tree
also drags the recent changes from sound.git tree for relevant part.)

In anyway, the whole patches were touching only sound/* files and no
changes in DRM side at all, hence they weren't sent to intel-gfx, I
suppose.

We've dropped the sound branches from drm-tip, mostly because they were
repeatedly rebased on Linus' master (as opposed to tags) during the
merge window.

ack, this is squarely on us Intel folks to ensure the test runs get done. 
This series did go through a number of Intel test setups, but 
unfortunately, as it now seems, not through the i915 CI setup that covers 
the affected configuration (audio DSP not used, HDA controller on the PCH, 
tests on the display audio codec).

Reproduced the problem now one one local setup and can confirm the fix 
Takashi and Maarten posted, does work.

Looks like a simple patch should be enough, can you test below?

Seems that we reached to the same conclusion :)

I took a quick look at other code paths, and sound/pci/hda/hda_intel.c
is the only place that needs the correction.  Other (ASoC) drivers are
either simply always returning the error or dealing only with -ENODEV
case for skipping the HDMI codec.


thanks,

Takashi

Yeah, the original comment in the code confused me and led me to not 
handle -EPROBE_DEFER in the first place there.

It's hard to judge without any log nor h/w details (as a typical bug
report from a developer :)

As a blind shot, does the patch below fix your case?
