When I try to decode it I get lots of

Failed to decode block code(s) and no output file is created.

libdcadec (one, which is now merged into FFmpeg) recognizes this file correctly:

dcadec.exe 1.wav

Is seems that spdif demuxer is to blame. When I rebuilt FFmpeg with --disable-demuxer=spdif, file was detected correctly.

Still broken and mpv/ffplay too.
