Hi, new member here, and thanks for the welcome aboard!! Didn't know this sight existed until I ran into trouble with my new marantz av. got it figured out but came across your site during my search for an answer . looks pretty amazing with a lot of up to date information. Anyway to my problem when I hook up my laptop to my av I get subwoofer feedback! Any ideas on how to solve/correct this? Thanks ahead of time for any ideas that may come my way! Jethro111
