This issue can't be reproduced on TGL -RVP with codec ALC711 in SDW mode and RT1308 in I2S mode, and issue #1709 occured on TGL -RVP with codec ALC711 in SDW mode and RT1308 in I2S mode.

This is the same bug as on:
#1847
The outcome is different as with HDA codecs, HDMI gets disabled but probe does not fail completely. With the SDW machine driver, if HDMI probe fails, the whole SOF probe fails and result is "no soundcards filed". This can be detected from this trace:
[ 4.676938] sof-audio-pci 0000:00:1f.3: codec #2 probe error, ret: -5
This bug is fixed by:
#1901

Issue can't be reproduced with sof-dev(commit:722d8e2) +PR#1901 +master(commit:f1fa3be9).

@kv2019i PR #1901 is still marked as Draft, is it ready to merge then?
Also I don't really get why there's a difference between SoundWire and HDaudio, should we add something in the machine driver then?
kv2019i commentedon Mar 19, 2020
@plbossart No, no, #1901 requires more work and needs to through intel-gfx. I'll submit a version to sof-dev once I get it through to the graphics tree.
And yes, sdw machine drivers are lacking support to disable HDMI at runtime. I.e. what I did in
3757a94
plbossart commentedon Mar 19, 2020
@kv2019i how can we force iDISP to disappear with codec_mask = 0? On CML devices there's no issue even when HDMI is not plugged in, this seems to be a TGL-specific issue?
sinahuang commentedon Mar 26, 2020
Test with sof-dev(commit: a27277) +master(commit: ae53aeb), issue still can be reproduced after PR1932 merged.
kv2019i commentedon Mar 30, 2020
The i915 patch accepted as well. Together #1957 (pending merge) and #1932 (merged) close this bug in sof-dev as well.
