Maybe somebody knows what's going on with it.Ever since I installed the Android Market via the youtube video, I constantly lose sound and the tablet keeps freezing up. When it does freezes, it either puts itself to the "Android" flashing screen on startup and just stays stuck there till I reset the tablet. When I do this I get the sound back until it does it again after it goes to sleep. Any ideas? This has been ongoing for a few weeks and almost at the point where I think this purchase may have been no good.
