I had this issue with my old computer but I built a new computer this summer. I didn't start having this issue consistently on my new computer until maybe mid-October.
I ran the troubleshooter. It said that the time to fall asleep was too long and that it fixed it. However, if I run the powercfg -requests command it still gives me the same error. So, I do not believe that actually fixed the issue.
There is no advanced power settings. There is Additional Settings. I went to that and my settings were already set to the defaults. I hit restore defaults anyways. But again I have the same error.
I closed all open active programs on my computer including Chrome and Discord. The only things I had running were Task Manager and Administrator: Command Prompt but I was still getting the notification that said that Realtek was using an active audio stream.
