I now have success playing an mp3 file using sox:

[root@kindle sox]# LD_LIBRARY_PATH=./lib ./sox /mnt/us/music/01-Diamond_Star.mp3 -t raw - | /usr/bin/gst-launch -v filesrc location=
/dev/stdin ! 'audio/x-raw-int,endianness=(int)1234,signed=(boolean)true,width=(int)16,depth=(int)16,rate=(int)44100,channels=(int)2'

So it is now possible to play mp3 files with a manually constructed command line. It should be possible to construct it programatically from the output of the soxi command:

root@kindle sox]# LD_LIBRARY_PATH=./lib ./soxi /mnt/us/music/01-Diamond_Star.mp3 

Input File     : '/mnt/us/music/01-Diamond_Star.mp3'
Channels       : 2
Sample Rate    : 44100
Precision      : 16-bit
Duration       : 00:03:26.92 = 9125172 samples = 15519 CDDA sectors
File Size      : 4.98M
Bit Rate       : 192k
Sample Encoding: MPEG audio (layer I, II or III)
Comments       : 
Title=Diamond Star
Artist=Point Valid with Catherine Asaro
Album=Diamond Star
Tracknumber=01/13
Year=2009
Genre=Alt. Rock

My next task is to add a compatible wget and add streaming support to sox here. Once that is working it is time to automate it and then build a KUAL menu.
