AMP was working fine with Pi B+ and Raspbian. Tried it with Pi 2. AMP not showing up in aplay -l
tried upgrading previously image with apt-get update, apt-get upgrade, rpi-update and reboot.
also tried downloading latest Raspbian Wheezy image.
what am I doing wrong? this site seems to suggest that it would just work out of the box.
