Lg Sound Bar Subwoofer Cutting Out. I can reactivate the sound by 1) resetting the tv audio settings ( changing from pcm to raw then back to pcm); 1.1 bluetooth interference 1.2 outdated software 1.3 hardware issues;

Subwoofer crackles while using optical connections. Or 3) by unplugging the optical cable and plugging it back in (either at the tv or the sound bar). Unplug the power cord from the soundbar’s back or wall outlet.
