Thank you - I'm now having a lot more success with txmuxer. I've created now some from the eac3to thd+ac3 files and they seem to work fine now. Also some created from DTS-HD tracks play fine too now, so it was just that I was using an old version.RESET_9999 wrote: Wed Feb 26, 2020 5:20 pm sounds like you are using the very old not open source version of tsmuxer which did not support uhd-bd properly
this version is the right one: 2020-02-23--01-10-39.zip

Thanks everyone for replies above r.e. lip sync. For the record my setup is:
X700 -> Sony AF9 -> Denon 3500 AVR (via eARC). But the lip sync issue with LPCM is there also if direct connect to the receiver.
In my experience playing video files with "normal" codecs such as TrueHD/Atmos and DTS-HD/X the X700 is spot on. It is only LPCM and Flac that it is iffy. I actually owned an X700 some time ago - and used it to watch my mkvs in HDR10. This rings a bell now about issues with LPCM (I ended up ripping everything back then as m2ts, to avoid needing to convert audio although I've since converted everything to mkv).
I think I'll keep the X700 rather than return as I was thinking too earlier today. The strides they are taking with tsMuxeR at the moment, perhaps it will soon become possible to create dolby vision and Atmos m2ts files from dual layer DV MP4s, in which case the lip sync issues might be gone and get DV.
Failing that I can consider physically re-ripping all my UHDs given @RESET_9999s observations above - getting DV and Atmos without needing to remux to MP4, but there are quite a lot of discs so I'll hold off for now.
