The Command Bar does not directly control your TV or cable/sat box. However, if your TV or cable/sat box supports Alexa Skills, you can enable the Skill for your device and control your device with voice commands through your Polk Command bar. For example, you can ask Alexa to change the channel, find and record your favourite movies and TV shows, or control playback for all your favourite content. For more information, contact your TV manufacturer or cable/sat box provider.
