update:
I check my syslog, which have interesting:

Apr 22 04:28:25 user pulseaudio[8149]: [pulseaudio] module.c: Failed to load module "module-alsa-sink" (argument: "device=hw:0,0"): ini
Apr 22 04:28:25 user pulseaudio[8149]: [pulseaudio] main.c: Module load failed.
Apr 22 04:28:25 user pulseaudio[8149]: [pulseaudio] main.c: Failed to initialize daemon.
Apr 22 04:28:25 user pulseaudio[8146]: [pulseaudio] main.c: Daemon startup failed.

the only problem is, I dont use pulseaudio...... my audio system should able to work without pulseaudio...
here is some similar situation but no workable solution

Re: no sound after a while

I have no idea what does the title mean and what is the problem. Your sound disappeared, you did reboot, sound is back - all is well?
Does the sound disappear now and again? Anything interesting in the logs?

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

sorry for the confusing.

I know its strange. looks like it will just go no sound randemly. 
I dont have auto sleep setting, but most situation it go no sound is during night and I remain my system opened, and when I wake up it goes no sound. there are few casees is happened in day times, when I want to watch some videos, it just go no sound.

after reboot sound is back, everything go back to work, after several hours it might go no sound again.
and logout dont work

something might interest is it will take much more time for turn off system when sound disppeared.

Re: no sound after a while

have you checked your system's log with journalctl for any errors when this happens?

also have you checked that your sound isn't simply muted or at 0% volume, speaker/headphone channel turned off or something similar?

I do check once before, but looks everything goes fine.[I will post it next time when it happen
and I do check sound setting, it is not muted or at 0%, both speaker and headset not working
