If AT&T TV doesn’t play any sound, plays sound out of sync with the video, or has other sound problems, try these options:
- Check the volume level and mute settings on your TV and any audio-visual (A/V) receivers you may have.
- Check audio settings on your device using your remote: Press the Home button, then Settings > System > Remote & Devices > Program Your Remote > Advanced Remote Program > Switch Volume Control.
- Make sure that your optical audio cable or HDMI cable is snugly attached to your device, the TV, and any A/V receivers.
- Connect your device to a different input to see if you can hear sound.
To enable surround sound, check audio settings on your device. Press the Home
button on your remote, then Settings > System > Audio > Audio Output
. The output options are Stereo only
or Surround Sound
