Hi,
I have recently swapped an old 5.1 system out with the Sonos Arc. The 5.1 system had all components connected into the A/V receiver with one HDMI from the receiver to the TV (Sony Bravia KD49XE8005) and had absolutely no lip sync problems.
I’ve now set up the Arc (via ARC) and, I thought, everything was still fine. I had no lip sync issues on apple TV, PS4 and some Sky content. Sonos Arc is connected via ARC (HDMI 3 in my TV’s case) with the Apple TV, PS4 and Sky Q box connected via other HDMI inputs.
However, I have identified a very specific issue with Sky Q. When watching stereo content (i.e. non HD) I have no lip sync issues. When watching UHD Atmos content (output via DD+), there are no lip sync issues. However, when Sky Q outputs DD5.1 the audio and video go out of sync in the way that can’t be fixed (i.e. video is ahead of the audio).
I have tried a power cycle and the issue still persists. Additionally, when I set the Sky Q HDMI output to normal and it outputs in stereo the audio and video are in sync.
I really want to find a solution to this because the Arc sounds great and Atmos content is brilliant, but lip sync issues for what is likely to be the vast majority of my TV watching is a bit of a deal breaker!
Any ideas?
Thanks for your help!
