The audio in my 4K TCL Roku TV is crackling, which I’ve read is the first noticeable issue when a speaker is blown, but the tv speakers were playing audio perfectly last night. When I connected my Magnavox sound bar to my TV using an HMDI cord, and play the audio ONLY through the sound bar, it’s still crackling. Which doesn’t make any sense because I’ve played music through the sound bar recently and it’s been perfectly fine as well. I’m confused as to what the issue could be, since it seems to be with both the TV and the sound bar. And if the speaker in the TV is blown then can it be fixed or do I need to purchase a whole new TV. Because I really cannot afford a new TV or sound bar, let alone both.
