Soundbar 500 Audio Dropouts
I have a Soundbar 500 with the companion bass module and the Nearly Invisible rear speakers. I have audio issues, similar to others have reported but slightly different. If I am watching a movie either through Apple TV 4K or through my Samsung 4K Blu-Ray player, I will get audio that stutters. This will typically start at about 45 minutes into whatever I'm watching but once it starts, it happens every 3-5 minutes. Pausing the movie and restarting will correct the stutter briefly. The audio sounds like it is rapidly dropping out and coming back, so all audio has a stutter when trying to watch.
The Soundbar is connected to my 55" LG OLED TV (2019 model) via digital optical cable. I have tried using HDMI ARC with the same result. I have factory reset both the Soundbar and the TV, with no success. I have also tried switching the HDMI cables and inputs connecting the Blu-Ray player and Apple TV, also with no luck. Finally, I have tried all audio output options on the TV and still have the issue (except when using 2 ch. stereo out from the TV, but what's the point?).
Considering this only happens when I am using the Soundbar, I believe it to be the Bose system - using just the TV speakers does not have this issue. Is there anything I haven't tried? Considering the relative newness of the Bose system, I am frustrated and disappointed.
