My speakers are directly connected to my maschine mk3. They emit a buzzing sound (in high frequencies) when maschine software is opened or when my maschine mk3 is in MIDI mode. I never had this issue before. The buzzing sound is not heard in the phones output on the maschine mk3.
My configuration is as follows : 
- PC running on windows 11
 - maschine 2 (last update)
 - maschine mk3 plugged in USB (no power supply)
 - Two yamaha HS7 connected to the maschine mk3 via line outputs
 - My monitors and my computer are wired on the same power outlet
 
I tried unplugging my peripherals, changing the line gain, changing the power outlet, changing the USB port but nothing worked please help.
Other observations : 
- The buzz sound is quieter when I plug my traktor s2 via line input
 - The buzz when the menu  for saving the project is open
