sudo modprobe snd_bcm2835
sudo amixer cset numid=3 1
mpg123 filename.mp3

設立 AirPrint：

sudo apt-get install avahi-daemon avahi-discover libnss-mdns cups cups-pdf python-cups
sudo usermod -aG lpadmin pi
# add "Allow from @Local" to Location section of / , /admin and /admin/conf
sudo vim /etc/cups/cupsd.conf
# add mine types for AirPrint
sudo echo '#
# "$Id: $"
#
# AirPrint type
image/urf urf string(0,UNIRAST<00>)
#
# End of "$Id: $".
#
' | sudo tee /usr/share/cups/mime/airprint.types > /dev/null
sudo echo '#
# "$Id: $"
#
# AirPrint
# Updated list with minimal set 25 Sept
image/urf application/pdf 100 pdftoraster
#
# End of "$Id: $".
#
' | sudo tee /usr/share/cups/mime/airprint.convs > /dev/null
sudo service cups restart
### go to https://raspberrypi:631/ and setup the printer
# download and run the airprint-generate script
wget https://raw.github.com/tjfontaine/airprint-generate/master/airprint-generate.py
