 The crashes are imo an independent issue, see ticket #7733, I believe that
 at least some of the programs you tested do not use FFmpeg for spdif

 Work-around is to use `-bsf:a truehd_core`, I don't think my receiver
 allows Atmos substreams at all, at least I was unable to find a muxing
 strategy that allows playback without stuttering (it is very easy to find
 a muxing strategy that does not overflow the spdif frame size for the
 sample you provided). My tests showed that the current strategy can
 definitely be improved though.
