Has anyone else noticed the slightest bit of lip sync on lossless content such as LPCM and TrueHD/Atmos since the 13.3 update got pushed? I never noticed this before, and my setup hasn’t changed (running my Arc through a Sony A90J).

I feel like the audio is now slightly ahead, and this wasn’t the case before. I have confirmed all settings on my tv, blu ray player, and Arc have remained unchanged.

Just to reiterate, this is only on lossless content that requires the eARC bandwidth. Lossy formats do not experience the lip sync issue (such as DD and DD+) on this new update.

I just tested a Dolby TrueHD/Atmos and DTS Blu-ray disc and I didn’t experience any lip sync issues. You might try unplugging the TV and Arc from power for a couple of minutes to see if it fixes it.
