Questions and answers
AFTER HOOKING UP A ROKU DEVICE I GET PICTURE BUT NO SOUND
Ensure the audio output settings on the TV and Roku are correctly configured. The TV's AUDIO OUTPUT terminal outputs sound at a consistent level and is not adjustable. Use the remote control to check the volume settings. Also, verify that the correct input source is selected and that the mute function is off. If using an HDMI connection, confirm that the Roku device is set to output audio via HDMI. If the issue persists, try a different HDMI port or an alternative audio connection.
