One channel is experiencing sound issues

If only one channel is missing sound or there is sound distortion, it may resolve on its own in a few minutes. Sometimes, Secondary Audio Programming (SAP) creates sound problems. If you're listening to SAP Dolby Audio, try switching back to the primary language:
  1. Press INFO on your remote control.
  2. Press the right arrow to highlight Audio/Video on the info bar.
  3. Select English Dolby AudioTM. (May vary depending on receiver type).

All channels are experiencing sound issues

The cause of the sound issues may be the remote control or audio/visual cables.

Check the remote control
Press volume up on the remote control. If the volume doesn't respond, you may need to program the remote control. Learn how to program your remote control.

Check the audio/video cables
Are you running cables from the receiver to your TV through another device, like a stereo or sound system? If so, follow these steps:
  1. Check that the device connected to the TV and the receiver are powered on.
  2. On your remote control, press TV INPUT to cycle through inputs, such as HDMI and HDMI3. If nothing happens, try programming your remote control
  3. If the problem persists, try connecting the receiver to the TV.
  4. If the sound returns, the problem is with the device connected to the TV and receiver. Refer to the device manual for instructions on how to change audio inputs and settings.

If you're not running cables from the receiver to the TV through another device, the issue could be the cable. Try tightening the cable connection or using a different cable.

Problems with sound synchronization

Try these tips to resolve the issue:
  • Change the channel. Changing channels helps to match up the audio sound and video.
  • Rewind the program you're watching. If you have a DVR, go back a few seconds, then fast-forward to return to the live broadcast.   
  • Using surround sound? Try using the TV speakers only to test if the surround sound system is causing the issue. Refer to the manufacturer’s manual for additional troubleshooting help.
