I own a Roku Ultra model 4660R I bought in 2017 and I'm all of a sudden having issues. When I plug in the headphones, the Roku sound either doesn't work, the Roku freezes, and/or resets itself. Idk why or what happened as I've used the headphone jack for years. I can't seem to find a remote replacement that has a headphone jack included. I have indeed seen many universal replacements and replacement on Roku site but non with darn headphone jack.
