Audio from external sources that send Dolby digital audio to tv are delayed when using Auto audio output mode. There is no delay when sending stereo only. It occurs when sending Dolby digital. Sources tried exhibiting the problem: TiVo Roamio DVR, Firestick 4K. Roku Ultra. Each connected to TV via HDMI cable. I used HDMI in ports 1 & 2. 3 is occupied by a q950t soundbar. 4 is connected to a Nintendo switch. TV audio delay is set to 0. Soundbar audio delay is set to 0. Sound is still behind/after the video. I tried resetting the TV, firmware is up to date for both tv and soundbar. Seems to be OK when output is set to pass through. Why is auto setting apparently broken and causing an audio delay? Do I lose any functionality (q symphony, atmos, other) by using pass through instead of auto.
