Samsung Soundbar HW-Q80R Audio delay
So i purchased the mentioned soundbar to get the dolby atmos experience, and i am having issues with lip sync/A/V sync issues, the sound is slightly delayed compared to video.
I dont have any set top box or streaming device, the sound goes directly from TV (LG UJ6517) to Soundbar via HDMI ARC, the media played is either youtube or netflix/hbo via the built in APP in TV.
I notice there is a delay in sound which i decreased by playing with A/V sync options in TV sound options, the issue is, the maximum negative value is -5 on the bar in the settings, i still notice approx 60-70ms delay so i would like to drag this option further to lets say -7, but its not possible, the SYNC option on the soundbar is only in positive values, meaning the sound would get more delayed and make it worse. What other options do I have? Maybe i can try to purchase a different cable than Samsung provides, such as HDMI 2.1 8k/60hz high speed gold connectors cable, would taht help? i am kinda hopeless here as i have tried everything to no avail.
Any help is appreciated.
