Welcome to Community@Insignia!
I'll be happy to look into this for you if you will please reply with your TV model number beginning "NS-".
Additionally, what is your audio/video signal source (e.g., disk player, cable box, etc.)?

Thank you for sharing the needed information.
Your TV will display the video and audio signal it receives. You may need to adjust the audio output settings on your cable box. If you need assistance with this, I recommend contacting Comcast Support at (800) 934-6489.
I hope this helps.
