Earlier on in this thread, there are many trials and things modified. It is better to try the latest set of directions from the wiki unless you are interested in modifying the index.html file or other parts yourself.

What are the complete steps you have done so far? Essentially you'll need to install OMVS or download the python server. Replace the index.html file, and place the sound files you require in the cities/voices folder (when you connect via cable and set to mass storage mode).
