SoundTouch 300 With LG 60UM6900PUA AND 4K Apple TV - Sound Cuts Out
Equipment: SoundTouch 300 soundbar connected to a LG TV 60UM6900PUA through HDMI ARC. Connected to the LG TV is a 4k Apple TV. All devices purchased in Dec 2019.
Issue: When watching content from the Apply TV the sound will cut out for about half a second then about a second later it cuts out again. This cut out always happens in a pair and happens at varying intervals. This is most noticeable when watching content with with constant sound, specifically sports with lots of background noise.
The sound bar does not do this when viewing over the air channels on the TV. I have played with setting on the TV and Apple TV with no resolution. I have also tried different HDMI cables as well as the optical cable provided with the soundbar. All devices have been updated to most recent software. I have also tried disconnecting and reconnecting everything as well as reset all devices and started over. Same issue persists.
Any thoughts on the issue would be appreciated.
