Hey I think I found it. There were no enhancement in the sound control panel, but like you suggested with your second link, Maxxaudio had the settings on multimedia, and I switched it to Off.
This is way better like that.
The noise is normal I guess ?
With noise reduction effect in Audacity :

On the enhancements in sound control panel, I saw that my devices were set in different modes :
16-bits 48khz
24-bits 48khz
I had the possibility to set them even in 192khz. Isn’t it better ?
Thanks anyway !
