Solved! I want to use a wireless headset for my TV with only a "digital audio output" available to use. What should I get?

Nov 11, 2018
My girlfriend who lives with me can't sleep with the TV on because of the audio. I sleep later than her and I enjoy watching TV late at night. I want to be able to watch TV without disturbing her and I was wondering if you guys can help me out on picking what to get.

This TV is an old sanyo 46" 1080p hdtv. Sanyo Model No. DP46841. Thank you for your advice!
