So, this is my second Sound Bar. First one was returned to Roku and replaced (via Roku). Now, the new one worked for about a month, then it just will stop all communication with TV, drops the pic, restarts the TV. Over and over, no matter what I am watching. Ive updated, reconnected the connections, power down, powered up. I have a Vizio smart tv. This is beyond frustrating Roku... how do I fix this, or is it even fixable because the last sound bar just would not connect to wifi or stay connected as well. My wifi is right next to the Roku as well.
