I am having sound problems with my XT Live. I can get sound from any patch, factory or custom. After about 30 seconds, the sound cuts volume drastically and amount of distortion, if using it. I haven't taken it apart and it's no longer under warranty, have had it since (approximatly) 2008. Not sure if I need to flash it, take apart and blow out the dust, but I need help definetly. Thanks.
