Bug 1489

Summary: Mix_LoadMUS not properly decoding vorbis files
Product: SDL_mixer Reporter: raptor85
Component: miscAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: unspecified   
Hardware: x86_64   
OS: Linux   

Description raptor85 2012-05-05 22:24:33 UTC 
Current HG build of SDL2_mixer all vorbis files loaded with Mix_LoadMUS produce a Mix_Music sample of just static noise on load with no error message set for either Mix_GetError() or SDL_GetError().  

The same sound file works properly if loaded as a Mix_Chunk with Mix_LoadWAV. Since the code is identical, compiling and linking it against SDL 1.2 both functions act properly, so this is a new error introduced in 2.0.

MixLoadMUS works fine however with FLAC, .it, and .wav files so far as i've tested, only vorbis files seem effected.

SDL_mixer was configured as 
./configure --enable-music-mp3=no --prefix=/usr --exec-prefix=/usr
to disable MP3 support (as current stable smpeg does not work with the HG source and I didn't need mp3 support)

libvorbis version is 1.3.2
