For those who are interested, github members can now download a testfork of tsMuxer that promises muxing TrueHD only. Haven't tested myself yet. Read from here: https://forum.doom9.org/showthread.php?p=1961685#post1961685
As a heads-up, I understand it's no longer required to download the fork for github members only. The feature and it's improvements also seem implemented in latest nightly builds. Download: https://www.videohelp.com/software/tsMuxeR or https://github.com/justdan96/tsMuxer/releases (no login required)
