--- Comment #3 from Scott shagooserver@gmail.com --- I was unable to find any raw streams that can be downloaded, however you can download sample mkv files containing muxed audio from https://thedigitaltheater.com/dts-trailers/
These are mkv files and need to be demuxed into their stream components by using mkvtoolnix and inviska mkvextract: https://mkvtoolnix.download/downloads.html https://www.inviska.com/mkvextract/
Just install mkvtoolnix (and do nothing else) and inviska then run inviska which will search for the mkvtoolnix installation then select a mkv file to demux (drag & drop). You only need to select the audio (DTS in this case).
Or I could send you one if you can receive large files.
Once you have the audio file, open eac3to with wine in a CLI and enter the command: eac3to <input_file.dts> <output.wavs>. (see my previous attachments)
Lets start this bug as the time issue as it is the most important.
Inviska is a appimage file so very easy but do NOT use a snap or flatpak installation of mkvtoolnix.
