If that worked for you great. I think the same optical glass is used in all of them but it is glass and if bent too sharply or jammed against something hard it will fracture and lose light conductivity. I tried a new TOS cable and that did not help for my drop outs. I thought I had it fixed with a settings change but the problem came back! I kept working on it and did find the reason for my dropouts though!! It was RF interference or a weak signal that killed the Blue Tooth connection. I had to move the subwoofer to within three feet of the sound bar with nothing solid between them. Now the audio is solid with no dropouts. The same problem can be caused by several things.

Not sure why that worked as optical digital cables do not get lossey. but hey it's something to try. I had the drop out issue too lately and think i have fixed it . My TV is the LG 55 oled with the LG sound bar, If the problem seem to happen only with a cable signal that is a strong indication the problem is with the cable box not the TV or sound bar. My cable box is the newer 1TB Technicolor unit with Spectrum. Anyway I had it replaced recently and that is when the drop outs became very noticeable. I went into the sound settings and started checking those. I found that Dolby Sound was for some reason set as off. I turned that to on and the drop outs ceased so it seems the sound bar wants a dolby signal to be stable. That's my experience.
