As a result of commit d2cd795c4ece ("ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen"), the sound output level on my machine, an X1 Carbon 7th gen, was reduced to ~65% of its previous level when playing certain sounds. [1]

Thank you for this work. Perhaps, Takashi will have some comments to improve this quirk.
Seconded - thank you!

It is possible that the X1 Carbon 8th gen would benefit from the same changes but I don't have a device to test that. Fixups are reordered so that the devices for 7th & 8th gen can share the same chain after the first fixup. The resulting chain is:
8th gen hardware should be similar, so the new fixup should be applied to this hw, too.
We'll do some testing here and confirm the fixes on the X1C7 and X1C8 (and Yoga)
Do let me know if there is any details Lenovo can provide that would help
