Can't wakeup from sleep. All hardware is waking up except SSD drive, maybe it is because that the nvme has entered power saving state.
Supported Power States
St Op Max Active Idle RL RT WL WT Ent_Lat Ex_Lat
0 + 9.00W - - 0 0 0 0 0 0
1 + 4.60W - - 1 1 1 1 0 0
2 + 3.80W - - 2 2 2 2 0 0
3 - 0.0450W - - 3 3 3 3 2000 2000
4 - 0.0040W - - 4 4 4 4 15000 15000
As a workaround, add the kernel parameter nvme_core.default_ps_max_latency_us=0 to completely disable APST, or set a custom threshold to disable specific states. For example, to disable PS4 set nvme_core.default_ps_max_latency_us=2000.

And the other way you can do with sleep problem:
BUY A NEW SSD DRIVE AND REPLACES OLD ONE. IT WORKS.
😄UPDATE: after update of alsa-conf-ucm to 1.2.10，microphone can be showed in control center correctly, and volume can be remembered after reboot.
Works with most recent sof-firmware(v2.2.5 or newer), but not perfect.
Sound volume too low, need to adjust volume using alsamixer, set DAC to 100%.
[Every boot] And need to set volume of HeadPhone in alsamixer to get a normal volume, or use command alsactl restore.
Microphone not working by default, use alsa-ucm-conf and select pro audio profile can see microphone device, but may cause other sound problems.
