Good Afternoon DVE,
Thank you so much for your taking the time out of your day to post to our community with your question. I’d be happy to help you answer the one regarding your 39” Insignia TV.
Your TV should be able to play the sound from your cable box, but if you have a higher grade service it may be time to upgrade your TV to get the best of out of your subscription. Please let us know if you have any other questions, and we’d be happy to continue helping you answer them too!

Thanks for your additional question. After reviewing the owner’s manual your TV only supports JPEG through the USB port. Please let me know if you have any other questions.
