I was at a concert and decided to record some footage for my wife who was unable to make it. When I replayed the video at home for her, the audio sound was WAY TOO LOUD AND CRACKLY. I turned it off as quickly as possible, but since then have noticed more crackling than usual in the speaker. Even some of the built-in noises casue crackling, at mid-volume. Now, I notice that MobiTV sounds pretty darn bad, especially when there's music in the background of what's on. From other people's descriptions/complaints regarding MobiTV, it sounds like my audio is worse.

So, any fix for a partially blown speaker? Any recommendations? If I take it back to Sprint, will they fix instead of replace? (I would definitely prefer fix as opposed to taking my chances on a new/refurbished unit.)
