Revision as of 05:01, 23 October 2012
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 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
- 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 non-GT series nvidia and oddballs.
- 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#.
