Alternate sound configurations can be set in /etc/pluto.conf. MOST sound cards should not require this.
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.
- All (Analog, Optical, Coax, and HDMI) are given the GT series extended scheme, including both the card# and device#.
