Summary of the bug:
When trans-coding an RTSP stream with WMA Lossless 24-bit audio to a WAV
file, ffmpeg produces many audible artifacts. Stream is publicly available
for testing: rtsp://djxmmx.net/rap-rnb. Please see next post for links to
the output files produced by ffmpeg.
How to reproduce:

[wmalossless @ 0000000002d04120] Arithmetic coding is not implemented.
Update your FFmpeg version to the newest one from
Git. If the problem still occurs, it means that your file has a feature
which has not been implemented.
[wmalossless @ 0000000002d04120] If you want to help, upload a sample of
this file to ftp://upload.ffmpeg.org/incoming/
and contact the ffmpeg-devel mailing list. (ffmpeg-devel at ffmpeg.org)
