"Reliable" and "Runs Amlogic vendor kernel" should never be used in the same sentence.
Is it then futile to try to achieve the goal of true Dolby Digital passthrough from a media player? If it is possible, kindly suggest a solution. (source media: remuxed high bitrate MKV's with possibly FEL 7 DV profile and high-resolution audio).
Thanks!
Your nVidia GPU card has Linux drivers that either require Kodi to run under Xorg which doesn't support HDR let-alone DV, or GBM/Wayland which supports HDR, but doesn't support DV, and LE doesn't support due to the lack of refresh-rate changing support for optimal playback. Our general advice for the last decade is to avoid purchases of nVidia hardware as future support in LE is not guaranteed. The exception is the nVidia shield which is still the Android reference implementation for Kodi. I understand that it supports DV, whatever that means. I hear the OSMC vero5 box is good too. I can't speak for what CE claims this week/month/ever.
Thanks for the information.
Is Nvidia card is the main problem here? If so, would switching to an NUC or another device (for example pii) result in LibreELECT being able to do it (end to end true Dolby Vision passthrough, that is)?
It can't, reliably or otherwise.
Thanks for the straight answer. Exactly what I was looking for 
Based on what you know, can CoreELEC do that on Amlogic S922X-J CPU based devices?
Hello.
Please advise if LibreELEC on regular ATX motherboard based "regular PC" with i7 12700 CPU and Nvidia GeForce GPU (GTX 1650) can reliably do end to end true Dolby Vision and high-resolution audio Passthrough when media files are played through PKC direct play.
I am after solving the problem of end to end true Dolby Vision passthrough using an external media player device. It's proving to be a Holy Grail. After extensive research, I have learnt that perhaps only CoreELEC and LibreELEC can do that reliably. Some other devices come close but not quite. For example, they cannot process FEL 7. Or, they fake the Dolby Vision badge, and that's it. Or, they cannot do passthrough of high-resolution lossless audio. Etc. Etc.
I have also read that CoreELEC on an Amlogic S922X-J CPU device (for example: Ugoos AM6B Plus) is the gold standard to achieve end to end true Dolby Vision passthrough. But that costs a lots of pretty pennies. I have a PC with an i7-12700K CPU and Nvidia GTX 1650 GPU that I would like to use with LibreELEC if I can achieve end to end true Dolby Vision passthrough--including FEL 7 with this setup. All my media library is in Plex. I will use PlexKodiConnect (PKC), and set it up to do "direct play".
If LibreELEC can do it, but only with an Intel NUC, please advise. I will then not pursue the "regular PC" route.
Thanks!
