Description Jason M. 2021-11-22 20:42:13 UTC 
I see repeated errors in dmesg like:

[   19.485990] snd_soc_skl 0000:00:1f.3: Blob NULL for id:1 type:3 dirn:0 ch:2, freq:48000, fmt:24
[   19.485997] snd_soc_skl 0000:00:1f.3: ASoC: error at snd_soc_dai_hw_params on SSP1 Pin: -22
[   19.486041]  SSP1-Codec: ASoC: soc_pcm_hw_params() failed (-22)


This worked using 5.14 up to and including 5.14.20 (I have not tried 5.14.21).

I started using the 5.15 line with 5.15.3 noticed these errors last week. Today I tried 5.15.4 where they persist.

Apologies I submitted the bug before finishing my comment.

I built 5.15.4 with this commit reversed and audio now works. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/sound/soc/intel/skylake/skl-topology.c?h=v5.15.4&id=87b265260046d4e0ed3f150dac2184b9dbd4bf7c

dmesg with snd_soc_skl errors

dmesg showing failures I see using 5.15.3 and 5.15.4.
Comment 3 Amadeusz Sławiński 2021-12-08 12:00:33 UTC 
Can you attach dmesg from working case?

And also provide dump of NHLT file (cat /sys/firmware/acpi/tables/NHLT > NHLT.bin)?

Additionally could you try with kernel build from: https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/log/?h=for-next
there were some additional changes made to NHLT detection and maybe they fixed this issue as side effect.

Audio did not work building from the fork above. I attached desg output.
Comment 9 Jason M. 2022-02-13 22:34:47 UTC 
I tried 5.17.0 RC3 today and audio is working again.
