I was messing with the settings and forgot to disconnect the battery. I was just ready to get it installed in the chassis I've been making and now no sound comes out. I rewired all the sound connections and nothing happens. All I did was remove and put the SD card back in. I had done this 3-4 times before it stopped working, so I assumed it wasn't a problem to do that. The worst I thought would happen is a corrupted card, but I scanned it and it's fine. Any suggestions? Did I fry anything? I certainly hope not....
