I am using Windows 10 and have Realtech speakers on my HP laptop.
On the initial install the speakers were working fine. On going to the program MAGIX, and doing what the intro video showed and changing the speaker function I started getting feedback from some source, the only other function I have installed is a Focusrite Scarlette Solo 3rd Generation USB Audio Interface. But I have changed it back and forth but the snowy sound still appears.
