[Windows] Just having MuseScore open and not playing anything blocks sleep due to audio stream being in use

Issue type

Other type of issue

Description with steps to reproduce

1. Install MuseScore on Windows (I tested with version 4.7.2, but this issue has been present for a long time)
2. Open MuseScore, you don't even need to open a file
3. Run powercfg /requests to observe that an audio stream is in use and is preventing the system from going to sleep
4. Close MuseScore
5. Run powercfg /requests again, notice that the audio stream is now gone

MuseScore should only have an active audio stream when actually playing in order to not interfere with the system going to sleep. This is especially important for laptops, but also for desktops. This also has a potential environmental impact, as computers will be left running that would normally go to sleep automatically if MuseScore is not running.
