Alternate sound configurations can be set in /etc/pluto.conf. MOST sound cards should work out of the box, and do not require this parameter. This parameter may be written by /usr/pluto/bin/nvidia-install.sh for various GT chipsets. This can be done at avwizard on the Audio Selector step 5, or at any time by running /usr/pluto/bin/SetupAudioVideo.sh NOTE: Audio/video should NOT be actively playing when running SetupAudioVideo.sh.
Below are example /etc/asound.conf files generated by these configurations. /etc/pluto/xine.conf files borrow the card# and device# (if any) as shown by the asound.conf
AlternateSC = null : Most cards function without this parameter, this is the default state.
- Analog, Optical, Coax and HDMI are treated the way they always have been, given only the card# 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#.
AlternateSC = 1 : Should only be necessary with some newer GT series nvidia that do not identify as second card or require backports, also supports other oddball devices.
- Analog, Optical, Coax, HDMI are given the card# and the device# to write to the confs.
AlternateSC = 2 : should only be necessary for HDMI oddballs that do not work under other two schemes, covers newer equipment.
- HDMI are given the GT series extended scheme, including both the card# and device#.
