Just recently purchased a Panasonic 50DX802B 4K TV. My current audio set up is everything going into the TV via HDMI and than Audio out to the SONOS Playbar, Sub & two Play:1's, i.e 5.1.
My issues start with HDMI 5.1 passthrough to optical out. Theres is an unusual, un-bearable delay where the audio is after the video. Unfortunately the SONOS lip-sync only works for video after audio.
5.1 audio from the built-in apps are fine with no lag and also with PCM/Stereo so its seems isolated to HDMI passthrough to optical.
I know they're solutions with an HDMI switcher etc and I will be trying an audio extractor via ARC later in the month. (something like this http://www.octavainc.com/HDMI-Audio-Converter-EDID-Manager.html
). The guys over at AVforums have also confirmed the same issue with their TV's.
I've seen positive results here, where SONOS have worked with Samsung etc to fix issues, I wonder can SONOS do the same with Panasonic (I've tried!)?
Has anyone used that ARC audio extractor with good results?
cheers in advance for your help
