I just set up my new SlingBox 350 and it worked great for an hour. Then the sound got scratchy. Then the sound disappeared. I restarted the laptop and then tried viewing on a different computer. Still no sound. I unplugged the box and still no sound. I checked my audio feed from TIVO which is good. Then I checked the cable, also good. Then when I checked the Audio out plugs there was no sound. I have come to the conclusion that the SlingBox 350 is broken because audio gets to it but doesn't get passed through to the out jacks or to the internet feed. How do I go about getting this box replaced or fixed?
