Sound Doesn't Work After Ended Process of Audiodg.exe

After ended process tree of audiodg.exe using Resource Monitor,my volume doesn't work. How to make my volume back to normal? Help me please.

I double-click on audiodg.exe and even tell it to run as administrator, but it doesn't?
I even opened a cmd prompt as administrator to see if there were any messages and there were none when I opened typed the command and executed it.
I know it will start if I reboot but that's the trivial solution.

Yes, I know the previous post is over two years old, but I just ran into this self-inflicted problem a moment ago and hoped someone might've posted another solution.

Thanks,
psi
