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.

By default the path name (i.e. the file name ; # minus the ".conf" suffix) is used as the lookup key, but if this option is ; # set, then the given string is used as the key instead.
