Audacity 2.3.3 resets Windows Microphone Boost

I’m using a headset with a microphone connected via 3,5mm jack (mic and line out in 2 separate jacks) to record audio. Unfortunately the mic is pretty quiet, which is why I have turned the volume to 100% and set the mic boost to +10dB in the Windows settings. This gives me a nice output level without any clipping and no noticeable static noise and works well for all kinds of applications (skype, games, etc).

The issue that I’m having is that the mic boost is reset to 0dB every time when Audacity is started. For some weird reason the slider in the Windows properties screen still shows +10dB, while it’s clearly not working. Sliding it to 20dB or 0dB and back to +10dB immediately brings the boost back to the desired level and it stays that way until I (re-)start Audacity. This is independent of the interface or device selected.
Other programs that record Audio do not change the boost.

Is there any setting that I can change in order to avoid this beavior, or is this an issue that should not occur?

System specs:
Audacity 2.3.3
Win 10 x64 (up to date)
ASUS ROG STRIX B450-F mainboard with a Realtek ALC1220 chipset, Realtek driver version 6.0.8895.1
No other tools, equalizers or effects installed or enabled.
No other recording or communication software running in the background.

Actually, it seems that this is not an Audacity problem, but an issue of Windows or the audio driver…

I have figured out that the mic boost is reset when the mic is not used by an application. Whenever an app starts recording after the mic was not used the boost is reset to zero.
I assume when Audacitiy starts it turns the mic off and back on, which triggers exactly this problem.

So far I have no solution, but it does not seem to be an Audacity issue.
