This audio issue was resolved for me with the SoC updates included in
stable linux-image:
5.10.0-21-amd64 5.10.162-1 (2023-01-21) x86_64
For reference, my machine info:
Product Name: 20QDCTO1WW
Version: ThinkPad X1 Carbon 7th
BIOS Version: N2HET68W (1.51)
Audio PCI info:
00:1f.3 Audio device [0403]: Intel Corporation Cannon Point-LP High
Definition Audio Controller [8086:9dc8] (rev 11) (prog-if 80)
Thanks for this bug report, the build info and revert patch for -20, and
for rolling in the additional SoC bits to make -21 work properly.
Kind regards,
Michael
