i had this problem for a while now and i think i finally found out what the problems are. Its the sound quality in windows settings. When i change it to 44Khz with 24 bits it doesnt scratch, but when i change it to 192Khz 12 bit it starts to scratch. It also scratches a bit when i strain the cpu or gpu in videos, movies or games, regardless of sound quality.
