I tried to encode and decode several different WAV files from CD rips with WavPack (version 4.60.1) in hybrid mode, on Arch Linux, on two different machines (Intel Core i7 and Xeon, x86_64). I always got the same result: the files are heavily distorted (groups of samples repeating themselves), and obviously non lossless. See samples.
I ran the following commands: CODE wavpack -b400 -c -m hybrid.wav wvunpack -m hybrid.wv wvunpack outputs the following: CODE WVUNPACK Hybrid Lossless Audio Decompressor Linux Version 4.60.1 Copyright (c) 1998 - 2009 Conifer Software. All Rights Reserved. original md5: e180f2ec2c4c65fd214bc6c4f70c7988 unpacked md5: 2d5edeb0d3d7ba971282428b77fd41c6 MD5 signatures should match, but do not! I tried the win32 binary, which worked fine (lossless result). I don't have another Linux distro installed anywhere to see if this problem is distribution-specific. I also tried three different builds (including one built from source by myself), always with the same result.

Got it! Thanks Bryant and Mr_rabid_teddybear for your assistance. The svn compile was throwing things into the wrong directories. After i figured out what the correct config flags should be all was well. Now i'm having an issue with files that have covers in the tags but that's another subject for another thread.
In short, the snv code works and fixes this bug! Thanks!! -------------------- Music lover and recovering high end audiophile
