Check the Basics

Before diving into more complex solutions, start by checking the basics:

• Volume Settings: Ensure that the volume on your TV and Roku device is turned up and not muted. Also, make sure that the audio output is set to the correct source (HDMI, optical, etc.).

• Cables and Connections: Verify that all the cables connecting your Roku device to the TV and audio system are securely plugged in. Loose or damaged cables can result in no sound issues.

• Power Cycle: Try unplugging your Roku device and the TV from the power source, wait for a few minutes, and then plug them back in. This simple power cycle can often resolve minor glitches.
