STEPS TO REPRODUCE
1. Open DigiKam
2. Run in cmd as administrator : "powercfg /requests" and confirm that nothing is preventing PC from sleeping
3. Open DigiKam and play a video (I run it from Album with Preview panel showing)
4. Close DigiKam
5. Run command again is getting me the following message :
SYSTEM:
[DRIVER] High Definition Audio Device (HDAUDIO\FUNC_01&VEN_10EC&DEV_0897&SUBSYS_10438814&REV_1004\4&e778799&0&0001)
An audio stream is currently in use.


OBSERVED RESULT

Computer won't go to sleep.

EXPECTED RESULT

I expect DigiKam to not block the process.

ADDITIONAL INFORMATION

I can run "powercfg -REQUESTSOVERRIDE DRIVER "High Definition Audio Device" SYSTEM" to circumvent this problem but it is causing other problems like not preventing the PC from sleeping while actually streaming audio/video.

I tested it here on my Windows 10 desktop machine. No problems are reported after running a video in digiKam via the command powercfg /requests.
You don't have the problem with other programs? For example play a video in Firefox?

You can really find a lot about this problem via google. Only that can be anything, from Cortana to an optical audio output.
Is digiKam still in the task manager after closing?

Yes it is running because I didn't close it. My problem is that it prevent the PC from sleeping while the app is open and only after I ran one or more videos. As soon as I close it, the audio stream is freed.

Of course no problemes are reported if you close DigiKam :) I don't have any problem with Firefox, when I play a video, the same driver is in use (preventing the PC from sleeping) and when I close the tab or even pause the video, the audio stream is freed properly like it should.
