Steps To Reproduce:
1 Disable FFmpeg by renaming the installed FFmpeg library file that Audacity looks for i.e. "avformat-52.dll" on Windows, "libavformat-52.dylib" on Mac or "libavformat.so.52" on Linux. 2 File > Import > Audio (or drag in) a native FFmpeg file such as wma or aac. 3 File imports as a few ms of screech using libmad but with no displayed error message to help user. 4 Repeat with 1.3.13 Beta. File import gives error stating file type (if dragged in), or explicitly requests FFmpeg (if File > Import > Audio is used).
Release Note:
GROUP: Imports and Exports Files that can only be imported using [http://manual.audacityteam.org/man/FAQ:Installation_and_Plug-Ins#installffmpeg FFmpeg] will import as a few milliseconds of noise (without error message) if FFmpeg is not available. '''Workaround:''' install FFmpeg to import these files, or use SUPER or iTunes to convert the file to WAV.

Description Gale Andrews 2011-06-25 19:26:12 UTC
Regression caused by fix for Bug 372 (MP2 files could not be imported without FFmpeg). Perhaps we need to stop libmad taking native FFmpeg files? It should not be a case of choosing one bug or another to live with because 1.3.12 both imported MP2 and threw an error when importing FFmpeg files with FFmpeg missing.

Fixed via patch from David Wallace in r 11229- see audacity devel ML for more info including tests.
Comment 2 Gale Andrews 2012-06-28 18:50:57 UTC
RESOLVED - FIXED (tested all three platforms). MP2 still imports fine. Thanks.
