Have a strange problem, when switching songs in xbox music app I get feedback, even though the sound is fine while playing. Noticed this also with a youtube app. At first I thought this has to be a hardware problem but when I accessed youtube through the desktop IE there is no problem. Also on the Metro side games are fine, no audio problems. Just curious if anyone else has experienced this, if not I am going to assume it is some app I've installed. Really appreciate any thoughts.
