Reg[6.5.1->6.5.2] Mutimedia dll is loading audio driver which prevents machine to sleep

Something is changed in Qt multimedia module of Qt6.5.2 which is not letting go windows in sleep mode at all. 

This can be easily reproduce with Qt's multimedia example Just run it with 6.5.2 and put the windows i sleep mode. It will not go in sleep because there is one audio driver which it loads and that prevents windows to go in sleep mode. 

Here is another way of testing it through command prompt:

-Run Cmd with as admin 

-Run command powercfg /requests

You will see 

DISPLAY:
None.SYSTEM:
None.AWAYMODE:
None.EXECUTION:
None.PERFBOOST:
None.ACTIVELOCKSCREEN:
None. 

Then run multimedia player (no need to load any media and play)

Then again run  powercfg /requests

ou will system audio driver is loaded. In my case I get following

 C:\Windows\system32>powercfg /requests
DISPLAY:
None.SYSTEM:
[DRIVER] Realtek High Definition Audio(SST) (INTELAUDIO\FUNC_01&VEN_10EC&DEV_0287&SUBSYS_17AA22FC&REV_1000\5&1f3ca26f&0&0001)
An audio stream is currently in use.AWAYMODE:
None.EXECUTION:
None.PERFBOOST:
None.ACTIVELOCKSCREEN:
None.

Found one more thing. It seems that there is binary break between 6.5.1 and 6.5.2 (if you try to use 6.5.1 library with 6.5.2 this does not work)
