I saw on the pi-top CEED kickstarter page that one of the push goals was to make a $15.00 speaker add-on for the pi-top CEED. Will this $15.00 add-on work with the standard pi-top as well as the CEED? Can you share (if you know) how this sound system will work? Does it connect to the 3.5mm 4-conductor audio/video connector on the Raspberry Pi 2.0? Does it connect to the hub somewhere and pull audio out of the HDMI system? Does it utilize a USB sound system and use-up to one of the USB ports? Do you know how big the speakers will be? Are they stereo? Will one have volume control from the pi-top keyboard volume keys on the top row?
When will they be available for order?
The updated the pi-top CEED web page to answer some of these questions. The project was fully funded, so it will be produced. The MONO speaker is about 2 inches square, and they will be available around the May/June 2016 timeframe. There is still no mention of where the connection method used to pick-off the sound.
It will work with 100% compatibility.
