I finally got around to testing this and it works now (quite load 
actually).   I haven't checked yet if the missing power or the timing 
improvements was the culpit.

Curriously, the mini-jack leaves something to be desired: my iPod 
headphones have to be inserted only so much to make the correct connection.

Tres cool.
