I don't know if this is a Xbox problem but I just need help troubleshooting.
My Xbox series X is connected to my Insignia smart TV via HDMI. My headphones (Arctis Nova 7p) connect to my TV through Bluetooth because my headphones are meant for pc, not Xbox, they don't connect to the Xbox. After yesterday, even though my headphones are connected to the TV, my Xbox audio goes through the TV speakers. All other TV audio correctly goes through my headphones. I don't know if this is related but I changed the HDMI audio to stereo uncompressed.
