The Soundbar I was using was from Orbitsound (Orbitsound A70). Ultimately Orbitsound took responsibility (as LG seems to be not interested in finding a solution) and they applied an update for the Soundbar that looks to have mostly resolved the issue I encountered. I do think that Orbitsound created an alternative fix to an issue that originated from LG. To me it is disappointing that LG appear to have not actively sought to find a solution to this issue that is affecting a lot of customers.
