Hi guys, any help would be much appreciated in advance. i don't have much of a clue when it comes to sound so i'm a little bit stuck. i'm sorry if this all gets a bit long winded! What i've got going on; I've recently spend £1000 on a new PC build but have small issues with my sound. i have an Xbox plugged into my mother board line in then a set of 5.1 Logitech speakers as output from my mother board I/O. The Xbox is connected via a VGA cable to my monitor with a RCA output.....http://tinyurl.com/bzfe4f6 That's then hooked up to a 2 to 1 aux 'thingy' then an aux into the output from my PC. i also have a pair of turtle beaches which i use for skype etc which i plug into the front of my case and switch the output to them and turn off the speakers. The issues; when i play games on my xbox i have a very strange echo type thing with sound....but only in game voices. almost like there's a slight delay between the right speaker and the left. this also occurs with the headset. the second issue is that when i have my xbox plugged into the line in there is a static even at relatively low volumes. any help here would be greatley appreciated, so if anyone could suggest anything would be fantastic. Thanks.
