YouView has its own volume control, separate to your TV. If you’ve set your HDMI sound setting to surround, then your YouView volume will be disabled. You would need to use your surround sound system volume control instead. If you’re not using a surround sound system then check the HDMI sound setting is set to stereo:
Open the Main Menu
From Box management select Picture & Sound
Select HDMI sound
Reset your remote
You might need to reset your remote control. We have a few different remotes so pick your remote here and try the instructions.
Restart your box
The old “switch it on and off” routine. Overused but it can often help resolve the issue. Press and hold the button on your box for 8 seconds, then let go. You’ll be greeted with a friendly ‘Hello’ telling you that your box has restarted.
We didn’t think you’d end up here, but thanks for trying all the above steps. We’d suggest contacting your box provider for further help.
