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.
Yup. Me too. New batteries. Re-paired remote.
I guess full blown factory reset is in order.
Did a factory reset fix the issue? I'm having the same problem now with my Ultra.
I re-paired the remote. Took a few times if I remember correctly.
i don’t think I ever did a full blown reset. But my memory for stuff like this is awful these days.
