why is my soundcard making my pa distort?
hi all, so i have my pa system, which consists of
a mixer *Pioneer DJM 350* , pre amp *Focusrite Saffire 6*, amp *crown xls 602* speakers *JBL JRX 115* and my laptop which is a Sony Vaio VPCEB4E4E, which has three usb ports - i have tried the usb of the focusrite in every port but no difference can be made.
and i know the system is working properly because when i use my brothers laptop there isnt any fuzzy hi pitch squeely (i think thats how its spelt) distortion sound, which is the problem
i always get the noise, when i have my cpu do a task, (even a simplistic thing such as scrolling up and down a webpage drives it crazy :( )
could someone please help me figure out what is wrong, thanks.
