So the problem seems to be the newly added quirk for fixing S4 issue
forgot the existing quirk for the speaker.  The patch below should
address the problem.  Please give it a try.

Subject: [PATCH] ALSA: hda/realtek: Fix speaker output on Thinkpad X1 Carbon Gen 12

The fix for S4 issue on some Thinkpad models in commit 1e707769df07
("ALSA: hda/realtek - Set GPIO3 to default at S4 state for Thinkpad
with ALC1318") caused a regression of the missing speaker output, as
the newly added quirk entry forgot that there was an implicitly
applied quirk matching with the pincfg, which determines the speaker
DAC connection and the I2S setup.

Correct the chained quirk entry to point to the right one,
ALC287_FIXUP_THINKPAD_I2S_SPK, to address the regression.

Fixes: 1e707769df07 ("ALSA: hda/realtek - Set GPIO3 to default at S4 state for Thinkpad with ALC1318")
