Your S3 is already activated : you have [deep] and ACPI : S3 :-)

It is suspend to ram, not to disk, is it that your have test ?

Like Vincent Morel say Are you sure the Legion is ALC287 ?

I have the same dmesg as you, but ehdaudio0D0 not hdaudioC1D0 and 2 line more :
snd_hda_codec_realtek ehdaudio0D0: ASoC: sink widget AIF1TX overwritten
snd_hda_codec_realtek ehdaudio0D0: ASoC: source widget AIF1RX overwritten
