This is why Samsung needs to fix the eARC on this tv. You either have compressed audio that can be out of sync with the picture or only get stereo sound. Very frustrating when it should pass through 7.1 channels via eARC.First, my setup. My PS5 is connected via HDMI into the labeled hdmi port 4 for gaming consoles (2.1 support). Next, I have an optical cable going from my tv to my Logitech z-5500 system. Ive had these speakers forever and I had the same exact connection flow with my PS4 and TLC tv without any audio delay issue.
so, the issue is... when I'm watch Hulu, YouTube etc the dialogue is out of sync with mouth movement. If I plug my headphones into the PS5, the issue goes away and everything is in sync.
the output device within the PS5 only gives me one option (hdmi device TV) . The other audio options are bitstream Dolby and dts. When I choose those, my Logitech picks the signal up and shows optical audio and I'm in 5.1 mode, but the out of sync occurs with each of those settings. If I switch the audio setting on the PS5 to linear PCM the Logitech goes into stereo mode and there's no out of sync occurring.
Any thoughts?
Have you tried changing the audio setting on the tv between pass through and auto?
