So yea I'm a hardcore audiophile and any crackle/pop in my music really p****es me off. I have had the EVO since Friday, and everything I try (Slacker, Pandora, last.FM, whatever) cracks/pops when the audio is going through the 3.5MM jack to my car. I'm already on a waitlist for replacement because I think it's faulty hardware. I've tried multiple cables and even HQ settings. Coming from a Touch Pro 2 which had amazing sound quality through the 3.5mm jack, needless to say I'm less than happy with the EVO since I primarily stayed with Sprint for uncapped data. If I get a replacement and it still continued, looks like I may be wandering over to that new iPhony. I urge everyone with this issue to post here so they can resolve it or figure out whats going on.
