AlternateSC = null: MOST cards function this way, default without a setting.

  • Analog, Optical, and Coax are treated the way they always have been, given only the card# to write to /etc/asound.conf and /etc/pluto/xine.conf
  • HDMI is given the card# and the device# to write to the confs.
  • nVidia GT series HDMI is automatically detected, and given a special set of values, also using the card and the device number.

AlternateSC = 1: Should only be necessary with old nvidia, or certain ATI/Intel GPUs over HDMI.

  • HDMI is given only the card#. The rest are the same as null.

AlternateSC = 2: should only be necessary for oddballs that do not work under other two schemes, covers newer equipment.
