Otoh, the following may work in theory:
$ ffmpeg -i input.aac -strict -2 out.dts
$ ffmpeg -f s16le -ac 2 -i out.dts -acodec copy out.wav

(44100 is the default rate)
In my test the bitrate was correct to my surprise (1411 kb), 
I believe it was completely off in the past.

This works with ffplay, testing with a hardware decoder is 
very welcome!
