The audio on my Vizio E48-DO television was going out when CNN goes to commercials or any other channel. All of a sudden audio goes out but picture stays. Spectrum went digital and they gave me a box to see digital channels. Problem stats right after that. I got it straightened as follows. First download app of vizio smartcast in your cell phone and pair the tv with it. find out the remote functions in it. Go to settings. Go to audio. Make sure it is on beatstream . Another thing make sure you put speakers on ON. once this is done it works like a new tv. Hope this help someone.
