That said, I've not had much luck actually getting anything out of the audio :-( I tried the guacamayo-image-mex-raspberrypi.rpi-sdimg which came up and gave me a nice display but it wasn't obvious how to import media and/or make it play. I tried copying some files manually to the SD card, but they wouldn't play either. Then I tried guacamayo-image-audioplayer-raspberrypi.rpi-sdimg and it was even less intuitive. Can you give me some guidance? All I'd like to do is play a simple (.wav) file on y RaspberryPi using pulseaudio.
