I hit some issues with my Meteor when it first arrived last week. Sound was off and it was showing odd digits during boot up. There was an Alltek MPU installed, so I cleared the memory (using the switches on the MPU) and then reset the MPU for Meteor. Cleared everything up. Manual for Alltek says sometimes you have to do this. Obviously this only helps you if you have an Alltek, but it sounded pretty close to what I was seeing so figured it was worth mentioning.
