Hi. I have a Q95T 2020 QLED TV, and a Samsung HW-Q70T Soundbar to which I added the rear speakers kit SWA-9000S.
Dolby Atmos, when coming from external HDMI source, has a 1-2 seconds delay.
- An Android TV box running VLC playing a Dolby Atmos media file, using passthrough audio
- TV is set to Q-Symphony (TV+Soundbar)
HDMI-eARC Mode to Auto
Digital Output Audio Format to Auto
Dolby Atmos Compatibility (selected and on)
- Cables are all eARC certified
The soundbar acknowledges Atmos is working. It is showing the DOLBY ATMOS label when playing starts.
However Atmos sound is delayed 1-2 seconds and there is a audio/video sync issue with video.
When playing regular stereo or 5.1 audio non-Atmos, sound is OK.
I suspect this may have happened since the 1497 firmware upgrade of the TV.
Any ideas, anyone?
