What to do if you don't hear audio from your Roku® streaming device

If you can see video, but not hear audio, first be sure that the audio cables are snugly connected to both your Roku player and your TV or AV receiver. Also check to see that the volume on your TV or AV receiver is at an audible level and that your receiver (if you're using one) is set to the correct input. If you still have audio issues, try a different audio cable or connect to a different audio port if possible.

If audio issues only occur when you’re trying to play content marked as 5.1 surround sound (indicated by a small "5.1" icon next to the parental guidance ratings), it is likely that your TV or AV receiver does not support Dolby Digital. In this case, switch the audio mode on your Roku back to "Stereo.” From the Roku home screen, select Settings>Audio.

Roku Ultra

If you are not hearing audio after connecting your Roku Ultra, try the following tips depending on your setup.

  • If you are using the Roku Ultra with a S/PDIF (optical) cable for audio output to a receiver, try changing the audio mode to Dolby Digital. On the Roku player, go to Settings>Audio and then select Dolby Digital for Audio mode. 
  • If you are connected via HDMI to the TV and optical to AVR, change audio mode to Dolby Digital/Audio/DD+/ Dolby D, DD+.
