It would be nice if the sox program was included as an external dependency:

Depends: sox, libsox-fmt-all

That would reduce the size of the package on the slimdevices server.  It would reduce download overhead for each squeezecenter upgrade since sox would already be installed.

I have not looked into which formats in sox are necessary to make squeezecenter to work, but I did a quick comparison with my SoX 14.0 version (Ubuntu 8.10)

Included in squeezecenter version, missing in Ubuntu version: amb cvu f4 f8 htk sndr sox wv

Missing from squeezecenter version, included in Ubuntu version: ao auto avi caf fap ffmpeg m4a mat mat4 mat5 mp4 mpg paf pvf sd2 sds w64 wmv xi

If there is a hard requirement for formats only supported in 14.2 a version dependency would need to be added.

This would also help with squeezecenter non-intel platform support.
