Same problem (so sound from internal speakers) here, with Legion Y740S.
Fixed it with adding to ALC285 quirks list to call alc285_fixup_ideapad_s740_coef.

sudo dmidecode | grep Family | grep Legion
        Family: Legion Y740S-15IMH

lspci | grep Audio
00:1f.3 Audio device: Intel Corporation Comet Lake PCH cAVS

lspci -v -s 00:1f.3 -n
00:1f.3 0403: 8086:06c8 (prog-if 80)
        Subsystem: 17aa:3825

Patched against ubuntu tag: jammy-stable-v5.15.76, but should merge with vanilla 5.17+, too. Will attach patch for reference, hopefully this will be merged to vanilla upstream.
