Issue: When Xbox One X is set to Bitstream out (regardless of DTS, Dolby Digital, Atmos, etc.) and TV is set to “Auto” audio output and/or XBox VRR is on, there is significant lag in the audio in game and streaming content.
Configuration: I have my Xbox One connected to HDMI port 4 (HDMI 2.1 port) on my 2020 Samsung Q80T (75”) via Monster HDMI 2.1 cable. I then have a Samsung HW-Q950T connected to HDMI Port 3 (eARC) with a full High Speed HDMI Cable (18 GBPS). All firmware is updated.
*I can eliminate the lag if I set the TV to pass through and turn off VRR on the console (needs to be both otherwise there is still lag)
*Uncompressed stereo is perfect
*Nintendo Switch works perfectly
*Swapped all cables out multiple times
*Tried replacing Soundbar with 2x different JBL 9.1s
*Completely restarted TV, Xbox, and Soundbar
*Switched Xbox back and forth to Stereo and Surround sound
*Tried turning off eARC
* Swapped Xbox HDMI ports
