I have an LG 50" 4k television (50UH5530) that I recently purchased. I have it connected to an OSD SoundSole 2.1 (virtual surround sound system) via the optical out. I had no problems with the audio on the previous TV, but with my LG television, regardless of what input or device I am using (live TV, video game console, Apple TV, etc) the sound cuts off, for about 1 second every 5-10 minutes. Anyone have any idea why this might be happening, or how to fix? TV problem? Speaker system problem? Help, thanks!
