Yes, this worked.
Basically, you go to trakt.tv, create a new API key and secret key, then edit the config file for Kodi, start Kodi, re-authorize trakt.tv through Kodi as you always do and it works like before.
Canāt speak to your specific situation, but Iāve got surround sound working with plex without problems. Iāve got the plex server app running on a Mac Mini, which is connected via HDMI to my surround receiver (which is in turn connected to the TV and the speakers). Iām using my Synology NAS as just a dumb backend, mounting my video share on the Mac via SMB.
To actually play stuff, Iām running the Plex Media Player on the same mini, with pretty much all of the audio settings at default.
Files with embedded DTS and other surround formats play properly in surround without me having to do anything.
If youāve had issues in the past, you might try using HDMI for your PC-TV interfaceāit seems to be the key.
Itās probably just a quirk of the way Iāve got things set up.
In my lounge I have a smart TV, an Apple TV, a TV recorder set top box, and a home theatre system - no dedicated media server. My NAS is my media server, and it is in my office.
All the appliances in the lounge are connected to the TV via HDMI.
When Iām playing something through the smart TV (media from the media server, YouTube, Netflix etc), it sends the sound back to the home theatre system via the return channel.
For some reason, when I run the Plex media server on my NAS I canāt get surround sound to work. Serviio does work pretty well for me though so I havenāt spent a huge amount of time trying to get Plex to work.
That sounds like the difference between our configsāI go HTPC ā receiver ā TV, and it looks like youāre going HTPC ā TV ā receiver. Not sure if thereās something quirky about how plex handles the return channel or notāsounds like there might be.
Lots of TVs (even new ones) donāt do surround passthrough - so if youāre hooking your media player directly to the TV and the TV to the receiver, the receiver will only pick up the stereo audio stream. The solution, as @Lee_Ars says, is to connect your media player to the receiver and the TV to the receiver - assuming that said receiver has HDMI switching.
Mine doesnāt, so I had my media player connected directly to my TV, and the TV connected via optical to the receiver. This allowed for surround sound when watching free-to-air but only stereo when using any other sources. So I now have the TV and HTPC connected to separate optical inputs and manually switch the receiver source with the TV. Clunky, but itās cheaper than buying a new receiver.
The TV does do surround passthrough - it works using Serviio, just not with Plex.
Given that the media server is in a separate room, connecting it to the receiver using HDMI isnāt an option. I could probably plug my Apple TV into the receiver, but then that would add another level of complexity to the equation and the rest of the family would probably kill me.
Serviio works. It doesnāt have some of the flash bells and whistles of Plex, but I can live with that
