Question about audio (windows player, from windows server)

I have a hopefully easy question here.
I run a server 2 feet away through a switch so everything is direct play with no transcoding
I’ve run in to a couple videos on my server that don’t play any audio at all unless i go in the plex player on the windows machine watching the movies and enable “exclusive audio” then it plays audio perfect. Am i doing something wrong cause im going from my pc to a dts/ac3 decoder set of speakers and aside from like 5 things out of 28000 everything plays fine. these are either encoded DTS or AC3 and before you ask, yes, i have many MANY more things encoded dts/ac3 and they play perfect 5.1, i’m just wondering why these 5 things wont play audio at all unless i set it to exclusive audio, i mean is that a big deal to begin with?

That can be misleading. Direct Play is not only a question of distance and connection speed.
But this is probably not the issue here anyway.

What type of connection is used between the computer and the speakers? If it’s HDMI, where in the chain do the speakers sit? At the end or in-between computer and TV?

Also, in the case of HDMI, did you explicitly select the audio output that you use or is it just set to “automatic”?

the 3 3.5mm cables from my pc to my 5.1 speaker set, hdmi isn’t involved since I watch on my 32" HDR samsung odyssey monitor. So it goes right from the computer to the speakers that do the decoding (there’s a optical jack too but i’ve only used the 3.5mm connectors)
Everything is set to automatic.

If you use the sound interface in the computer, you need to:

  • set the number of speakers correctly in the Windows settings
  • in the same settings dialog of Windows, disable all “Enhancements”, and set the default sample rate to 48 or 96 kHz at 24 bit (if available)
  • select the actual name of the audio output in the settings of the Plex player (i.e. not to “automatically”)
  • set the number of audio channels to 5.1 in the settings of the Plex player
  • make sure that the volume slider of the player software has not been set to 0 (sorry, I had to include that)

Also, if you use analog cables, then your speakers have nothing to do with DTS/AC3.

If there are still these 5 aberrant files, you should look a little closer at their media info and compare that to the media info of files which play normally. Take a particular close look at the sample rate and the audio codec.

yep, disabling enhancements and setting it to my onboard audio fixed those five files.
I think it was the enhancements but they all play fine now
thanks!
