And to further my correction, buyer beware, check for the ports.
Raspberry Pi had several different pre release models. In production I think there are 2 or 3 boards. Unsure if they all are the same, aside from RAM differences.
The 512MB Rev B board has HDMI and the 3.5mm audio output. Assuming you can get audio out via the HDMI also.
No audio input on any of the models though.
