# using a B+ and the default skeleton app I get no startup audio on a B+.
# pi 2 works perfectly.
# I can control audio from the webpage fine.
# This is what I did:
diskutil list
diskutil unmountDisk /dev/disk2
sudo dd bs=1m if=~/Downloads/2016-02-26-raspbian-jessie.img of=/dev/rdisk2
Put it in the Pi, login, expand the filesystem, reboot and login again.
