The audio on our Roku Express has started to go in and out every couple of minutes, sometimes not even that long. I have unplugged EVERYTHING, and replugged it in. I have changed out the cables, tried different HDMI ports on the TV, gone into settings and restarted, unplugged all the cables on my internet modem. NOTHING WORKS!!! Does anyone know how to fix this, because at this point I'm ready to throw my Roku in the dumpster and find something else to use to stream with. We have had this device for about three, maybe four years.
