On the newer builds of the Raspberry Pi, the audio output is not high enough to program Edison, as such additional amplification is required. This can be achieved via plugging Edison into: a monitor connected via HDMI, the headphone jack of a powered set of speakers or USB sound card. Visit eBay for low-cost USB sound cards.
