This ; is used as fallback for all cards that have no special mapping ; assigned (and should be good enough for the vast majority of ; cards). If you want to assign a different profile set than this one ; to a device, either set the udev property PULSE_PROFILE_SET for the ; card, or use the "profile_set" module argument when loading ; module-alsa-card. ; ; So what is this about? Simply, what we do here is map ALSA devices ; to how they are exposed in PA. We say which ALSA device string to ; use to open a device, which channel mapping to use then, and which ; mixer path to use. This is encoded in a 'mapping'. Multiple of these ; mappings can be bound together in a 'profile' which is then directly ; exposed in the UI as a card profile. Each mapping assigned to a ; profile will result in one sink/source to be created if the profile ; is selected for the card. ; ; Additionally, the path set configuration files can describe the ; decibel values assigned to the steps of the volume elements. This ; can be used to work around situations when the alsa driver doesn't ; provide any decibel information, or when the information is ; incorrect. ; [General] ; auto-profiles = no | yes # Instead of defining all profiles manually, autogenerate ; # them by combining every input mapping with every output mapping. ; ; [Mapping id] ; device-strings = ... # ALSA device string. %f will be replaced by the card identifier. ; channel-map = ... # Channel mapping to use for this device ; description = ... ; paths-input = ... # A list of mixer paths to use.

A decibel fix is a table that maps volume steps ; # to decibel values for one volume element. The "element" part in the ; # section title is the name of the volume element. ; # ; # NOTE: This feature is meant just as a help for figuring out the correct ; # decibel values. Pulseaudio is not the correct place to maintain the ; # decibel mappings! ; # ; # If you need this feature, then you should make sure that when you have ; # the correct values figured out, the alsa driver developers get informed ; # too, so that they can fix the driver. ; ; db-values = ... # The option value consists of pairs of step numbers and decibel values. ; # The pairs are separated with whitespace, and steps are separated from ; # the corresponding decibel values with a colon. The values must be in an ; # increasing order. Here's an example of a valid string: ; # ; # "0:-40.50 1:-38.70 3:-33.00 11:0" ; # ; # The lowest step imposes a lower limit for hardware volume and the ; # highest step correspondingly imposes a higher limit. That means that ; # that the mixer will never be set outside those values - the rest of the ; # volume scale is done using software volume. ; # ; # As can be seen in the example, you don't need to specify a dB value for ; # each step. The dB values for skipped steps will be linearly interpolated ; # using the nearest steps that are given.
