Volume Issues

I've been having this issue as well for about the past week, maybe longer. Sou d just ramdomly goes out. Sometime it comes back on in a second or 2, and other times I have to change the channel, then change it back and it instantly fixes this. I don't know is its in connection or not, but at about the same time all my streaming apps on the contour boxs started lagging and are as of today unwatchable(Netflix, Hulu, Prime, and Paramount+ just as example.
