Look into using ffmpeg directly, or even something like sox.

My use of mplayer in particular was due to its availability on the site here for the kindle. I used it first on my K3 where audio output was built in. Other options as you noted are available, but I am unaware of binaries for our kindles.
Beyond that the problem of building the gst pipeline with the proper rate and channel count remains. With a WAVE header this is self defined, but the available gst elements on the kindle do not support this.
This suggest to me we need a program of some sort to accept the source to be played, which might be a local file or an internet stream, start playback to a buffer, create the gst pipeline with the rate and channel count defined from the source header and pipe the decoded raw pcm from the buffer to the gst pipeline for playback.
I am beyond my experience level in creating such a program to be run on the kindle, my limits here are simple scripts and probably creating a KUAL extension to make use of them. Hopefully someone else can expand on this.
I should note that the original question that started this topic is now answered, a converted audio book of any sort can be played with this approach.
