HDMI output with ALSA

#   ALSA improvements for Debian Wheezy
#   2014-05-03,  ed <irc.rizon.net>
#
#   This does the following:
#     - Sets HDMI output as default
#     - Adds dmixer (multiple sources)
#     - Adds softvol (volume control)
#
#   Use aplay to find required device IDs:
#   $ aplay -l
#     - card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
#     - card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
#
#   Save this to your .asoundrc then restart alsa:
#   # nano /home/ed/.asoundrc; service alsa-utils restart
#
#   Finally, to set the volume:
#   $ amixer set fgsfds 50
