If so it is added to the list of mixer +; elements PA will control, keeping the order it read them in. If a +; mixer element described here has set the required= or +; required-absent= directives a path might not be accepted as valid +; and is ignored in its entirety (see below). However usually if a +; element listed here is missing this one element is ignored but not +; the entire path. +; +; When a device shall be muted/unmuted *all* elements listed in a path +; file with "switch = mute" will be toggled. +; +; When a device shall change its volume, PA will got through the list +; of all elements with "volume = merge" and set the volume on the +; first element. If that element does not support dB volumes, this is +; where the story ends. If it does support dB volumes, PA divides the +; requested volume by the volume that was set on this element, and +; then go on to the next element with "volume = merge" and then set +; that there, and so on. That way the first volume element in the +; path will be the one that does the 'biggest' part of the overall +; volume adjustment, with the remaining elements usually being set to +; some value next to 0dB. This logic makes sure we get the full range +; over all volume sliders and a very high granularity of volumes +; already in hardware. +; +; All switches and enumerations set to "select" are exposed via the +; "port" functionality of sinks/sources. Basically every possible +; switch setting and every possible enumeration setting will be +; combined and made into a "port". So make sure you don't list too +; many switches/enums for exposing, because the number of ports might +; rise exponentially. +; +; Only one path can be selected at a time. All paths that are valid +; for an audio device will be exposed as "port" for the sink/source. + + +; [General] +; type = ... # The device type.
