I didn't want to cut it too badly, since that can disrupt how it
works, so its a bit sizeable (the bitrate is also quite high), its the
first ~4 minutes from the start of the Incredibles 2 UHD Blu-ray

https://files.1f0.de/samples/incredibles2-truehd-bitstreaming.thd
(TrueHD stream)
https://files.1f0.de/samples/incredibles2-truehd-bitstreaming.pcm.xz
(bitstreaming output, xz compressed)

There should be a few occurances of this particular case, its the same
stream I used to look into these problems in the first place after it
was reported to me by users.
