Fellow Audioholics,
I am currently flummoxed by an AV sync issue between my (new) SR7015 receiver and my LG C1 OLED. Any ideas, suggestions or solutions are welcome. It all started a couple weeks ago when I upgraded my 7.1 HT system to 7.1.2. The original 7.1 system passed a 4K ATV, a STRDN-840 blu-ray, and a PS5 through a Marantz SR5010 into an LG C1 OLED. The experience of receiving such an immersive payload was satisfying. In case you're curious I employed short, but thick, audioquest cinnamon HDMI cables to allow for each player to comingle with the SR5010.
I soon decided I was going to give ATMOS a try. So, I picked up some SVS prime elevations to use overhead and upgraded my SR5010 to a SR7015 which gave me more channels to enjoy. Setup was a breeze. I simply transferred the connections from the SR5010 to the SR7015 and added the 2 height channels. This was two weeks ago. Since, I have been constantly fiddling with LG settings and the Marantz knobs. No matter what I try, I can not get the audio to sync with the video... on BR discs, on ATV apps (Netflix, IMovies, Prime), or on apps played from the PS5. The audio appears to be many milliseconds behind the video across components. Attempting to correct this with the Marantz audio delay tool I realized each app has a different delay. The same was true for the LG C1 delay tool. I tried both the standard and eARC HDMI outputs on the SR7015. None of this had much impact on the sync issue.
I wondered if it could be the Marantz... So, I had an old, but reliable, 32" ViewSonic ultraHD monitor which I connected to the non-eARC output of the Marantz. This resulted in all apps/components playing in sync... everything looked good.
So, it appears the SR7015 and the lg C1, don't like one another, and it's really got me down. Do I return the SR7015 and get something else? How do I know this won't happen with other receivers... is there any gossip on who likes the LG C1?
There was one PITA solution. The only way I can regain the joy outlined above, while experience head immersion, is by sending the ATV into the LG and sending the LG audio through the SR7015 via eARC. However, doing this just makes me more upset, as I paid good cash for a receiver that is designed to handle this passthrough.
has any one encountered something like this? What was your solution?
