Description

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:

ffmpeg -i "D:\Downloaded\02 - Ascension.wv" "D:\Downloaded\02 - Ascension.wav"

It cannot decode 16 channels wavpack too.
