Also, your solution seems to work on yoga models, I didn't see anyone with legion model saying it worked for them. Here are my outputs:

cat /sys/power/mem_sleep
s2idle [deep]

sudo dmesg |grep ACPI|grep supports

there is something weird about this last command: the speaker_outs is set to 0

I tried suspending the machine after playing some music but did not get audio after waking
