I have a Roku Streambar (model # 9102R, serial # YL00FC864082) that has developed crackling, buzzing, and popping recently. It did this on all channels, as well as while being used as an internet speaker. This is the second Streambar this has happened to; the first one I threw away as I figured it was a blown speaker.
I tried restarting the Streambar, unplugging it overnight, and deleting and re-adding channels. These didn't help. Turning off the bass helped somewhat. I've just reset factory settings, and this has helped for using the Streambar as an internet speaker for Spotify.
Has anyone come up with a solution for this problem? If not, I have been in the Roku ecosystem for so long, are there better options for internet TV--Apple TV, Chromecast, Amazon? It seems like there is a manufacturing or software problem with the Streambar.
