I had the same issue with a Vizio E Series tv. I tried the advice read here in disconnecting the power supply to the cable box. It didn't work. I then unplugged the TV and the sound returned. Not sure what caused the problem.

I had the same issue with a Vizio E Series tv. I tried the advice read here in disconnecting the power supply to the cable box. It didn't work. I then unplugged the TV and the sound returned after plugging it back up. The Vizio app for Android required resetting. Not sure what caused the problem.
