I wrote a program for reading a SD card and playing the sound on it. It can also take sound from the computer over the UART and load it into the SD card. You send the nerdkit 'l' and then PCM data in binary. use libsndfile (google it) and pcm2nlsv to get PCM audio with values separated by newlines. Here's a pinout of a SD card

pinout

and the connections are this: SCK -- 1.8K -- SD pin 5 -- 3.3K -- GND MISO -- SD pin 7
