Onn soundbar says "talk" anytime I use the OK button on roku remote
I have a roku 55 inch TV and an onn soundbar. I have the soundbar connected through optical, sounds fine and works well. Everytime I use my roku remote to make a selection with the OK button on an app like spotify for example the soundbar says talk. It interrupts the audio to do this. It's especially annoying when typing in a search, each letter the soundbar says talk. How do I turn this off?
