LE 8.90.006 DTS-X MSTR audio glitches with Coffee Lake

I've installed LE 8.90.006 on a Coffee Lake NUC (NUC8i3BEH) and keep getting glitches in the audio for DTS-X MSTR and Dolby TrueHD tracks. I've enabled audio passthrough for all formats and I'm connected to a Marantz SR6010 AV receiver with HDMI 2.0. The glitch is a minor pause in the audio track that sounds like a small click. This doesn't seem to happen with DD5.1 or regular DTS tracks. And of course if I disable the "Allow passthrough" option it works ok.

Here are the logs when I play a simple DTS-X sample:

Could you add:

Code

INFO: ID:0x185 Name:3840x2160 Refresh:23.976000 Width:3840 Height:2160

to your Whitelist please? The 23.98 fps sample is played at 60 hz - which is not good for PT audio (running at wallclock).

That did it. Error code PEBKAC for this case then. Whitelisted all 1080p and 2160p refresh rates that are supported by the TV.

Thanks Fritsch, much appreciated.
