Hi all

We put up a demo stream with the Cirrus Logic audiocard and the Pi A

• on the map and at

http://locus.creacast.com:9001/london_cirrus.ogg

The soundscape here is quite muddy with both high and low frequency 'noise' so not ideal for testing but..

The Cirrus sits on top of the Pi and now provides bias voltage to the Line In

So this demo uses a pair of Primo EM-172-Z s plugged directly

Result is very low cost and power usage suitable for solar applications?

Our aim is to add the Cirrus drivers to the excellent new disk images available at Locus Sonus
