No Sound from the Television (Wii U)
Wii U
The information in this article can help you when no Sound comes from the Television when using a Wii U.
Note: If you are attempting to use surround sound, you may find our information on Surround Sound Is Not Working helpful.
What to do
If you are using a receiver, switch, or other device, see if sound will continue after switching applications (such as Mario Kart 8 to Netflix, or Netflix to the Wii U Menu). If this solves your issue, then please use it in the future and be sure to keep your system updated.
For testing purposes, please connect the Wii U directly into your television, bypassing any receivers, switches, or other devices.
