My system constitutes a Sonos Playbar connected to a Sony XBR55X850C television. The audio connection is by an audio optical cable. The television is also connected to a TiVo. When pressing the fast forward command for the TiVo, a popping noise is produced by the PlayBar. I have tried searching the forum and have not found this issue, but I may have missed it. If anyone knows how to fix this I would appreciate a comment.
Otherwise, great sound from the PlayBar.
