If Jellyfin is able to direct play the content, it simply passes the audio of the source file through completely unmodified. So my guess is that, if the audio is actually being converted to something other than source, it's your TV that's responsible. 5.1ch PCM audio IS a thing that exists though. So you might simply be wrong about the number of channels on the PCM audio track.
