mplayer: extract audio to PCM to stdout

First the obligatory disclaimer: Yes I googled. Yes I checked the man page.

OK then.

I would to have mencoder/mplayer read a video file and output just the audio part as PCM (raw 16 bit) to stdout. The -dumpaudio option does not do this. The -dumpaudio option dumps the audio as is, not converting from the input codec to a "proper" raw format.

In a perfect world I woudl type something like this:
mcoder some_video_file --just-the-audio-pcm-to-stdout-yes-please | sox <various sox options>
Thank you in advance.
