Hi all ! First off I'd like to introduce myself, since this is my first post ! Nice to meet you all and finally be active in a forum I have read a lot previously ! My issue, to which i can't find a solution or a similar case, is that sometimes, without warning and in no perticular configuration, my MacBook will play an awfull noise when listening to my music through my dac (connected by USB), but not just distorting it in a lightly unpleasant way, not just small clicks and pops, but a really fuzzy sound, as soon as I touch my trackpad or keyboard. I'll try and post a video to make it clearer. The only way I can get rid of it is to wait for a few seconds.. If anyone has an answer it would be welcomed ! Thank you !
