Qt Multimedia backend can prevent windows from sleeping

[Athameral]

Describe the bug
As described in the title, Qt multimedia prevents windows sleeping.
Note that once the player constructs, it starts to use the audio device, until the entire program exits.
I tried to destruct player, via unique_ptr and so on, but it did not help.

Maybe consider adding FFmpeg backend back 😶.

To Reproduce

Just type powercfg /requests in the terminal.

I saw the changes in your branch. Maybe try bumping this to 6.8.1 to exclude the possibility of Qt bug?

qt_ver: [ 6.6.3, 6.7.2 ]

We are stucking in 6.7.2 because of #1738 , sadly 😅

Maybe we do not have to wait for the ffmpeg to fix the speex bug. Anyway it is the upstream bug. not our responsiblity to wait for them.
