I unfortunately couldn't find samples on the MS website (perhaps I'm
using the wrong browser ;->), but I can confirm that the
libavcodec/wma.c and wmadec.c known only about "version 1" and "version
2" WMA.

Actually, digging further, 0x162 is "Windows Media Audio Pro".

There's a link in that articles to samples on the mplayer website:
http://samples.mplayerhq.hu/A-codecs/WMA9/wmapro/
and indeed they don't play with libavcodec or in ffmpeg.

D'uh.

P.S.: Thanks, Microsoft.
