QN90C using optical audio out with a DAC and TV speakers on. TV audio remains sync'd with video. Problem: TV audio delay control must be set to 100 to sync the optical audio output with the TV speakers using antenna input. TV installed app this setting must be moved to 0, HDMI input requires a setting of 180. This is a real pain in the butt to keep changing the delay!! Is there any update/hidden setting/ that would keep the audio sync'd between the optical and TV speakers??
