Summary of the bug: ffmpeg can't properly decode WavPack file 24bit/44.1
kHz that is created with official WavPack comandline tool with parameters
-hhx3. Decoded file contains silent sections. WavPack comandline tool
decodes this file without problem. If decoded wav is encoded to WavPack
again using ffmpeg encoder with -compression_level 3, ffmpeg can't
properly decode it too.
How to reproduce:
