Steps to reproduce the problem:
1. Go to a website that streams audio/video. Stay on the site for a period of time
2. Close the tab containing the streaming. Only keep one empty tab open.
3. Run the command 'powercfg/requests'. You'll notice that Windows indicates that a stream is in use. However, no audio stream is active. Chrome is the only program running.
4. Close Chrome. Run 'powercfg/requests' again. You'll notice that the indicator of an audio stream is gone.

What is the expected behavior?
Windows 10 is showing an audio stream in use and this is preventing Windows 10 from going to sleep.  This is normal behavior since you don't want Windows sleeping if your streaming audio. However, I think Chrome is sending Windows the info regarding the audio stream when all I have open is an empty Chrome tab. There is no web site displayed or any audio streaming and Windows still indicates that an audio stream is in use. I have no other programs running. I just have Chrome running. Also, if I close Chrome, Windows no longer displays that audio streaming is in use. The indication of streaming always disappears whenever I close Chrome. Chrome should release the audio driver when a tab containing audio is closed. 

What went wrong?
My computer will not enter sleep mode since Windows thinks Chrome is streaming audio even when an empty tab is open. Closing Chrome releases the driver and allows the computer to sleep.

This problem is happening on a fairly regular basis. I'm unable to give exact instructions on how to recreate the problem. Sometimes I can stream audio, close the tab (with streaming audio), and verify that Windows is not indicating audio streaming. There are other times when I stream audio, close the tab (with streaming audio), and verify that Windows is showing audio streaming when all I have open is an empty tab in Chrome.

picture1: Chrome running one empty tab. Windows is showing that audio is streaming. Windows will not sleep.

picture2: Chrome has been closed completely. Windows is showing that no audio streams are present. Windows will now sleep.
