Comment (by Balling):

 Okay, so encoder of 24 bit files is bitperfect (yes, actual 24 bit with
 all bits are sometimes set, also I used -c:a pcm_s24le to convert back to
 wav and then back to truehd all on 30 bit activation commit) can only do
 up to 5.1 (not mono and stereo, as it says, '''it cannot do mono too''',
 BTW). Yet, apparently my LG C9 does not recognize such 5.1 files as being
 TrueHD... (And no, -sample_fmt s16 does not help either.) So 5.1 is not
 '''conformant'''. I also suppose that indeed this issue is just a bug in
 the decoder, maybe in 8.1 part of it.
