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 should NOT be actively playing when running SetupAudioVideo.sh.

Auto-detection is attempted when specific packages are installed, or if the pluto.conf "AlternateSC" setting is null or = 0. In most cases, this value will never exist.

Below are example /etc/asound.conf files generated by these configurations. /etc/pluto/xine.conf files borrow the card# and device# (if any) in the same way as the asound.conf

AlternateSC = null : Most cards function without this parameter, this is the default state.


AlternateSC = 1 : Should only be necessary for analog multi-channel.


AlternateSC = 2 : Should only be necessary for oddballs that do not work under other two schemes, covers older equipment. This additionally changes the xine.conf scheme.

xine.conf

In conditions of null, 0 values of AlternateSC for multi-channel audio, the last 4 lines of /etc/pluto/xine.conf looks like this 

audio.device.alsa_front_device:plughw:0,3
audio.device.alsa_default_device:plughw:0,3
audio.output.speaker_arrangement:Pass Through
audio.device.alsa_passthrough_device:plughw:0,3

In the case AlternateSC = 1, some sound cards cease functioning when the Pass Through arrangement is specified, instead of just the passthrough device. 

audio.device.alsa_front_device:plughw:0,3
audio.device.alsa_default_device:plughw:0,3
audio.device.alsa_passthrough_device:plughw:0,3

All stereo analog appears like so: 

audio.device.alsa_front_device:plughw:0,0
audio.device.alsa_default_device:plughw:0,0
audio.output.speaker_arrangement:Stereo 2.0

Except in the case of 2, when it appears like so: 

audio.device.alsa_front_device:hw:0
audio.device.alsa_default_device:hw:0
audio.output.speaker_arrangement:Stereo 2.0
