; Default profile definitions for the ALSA backend of PulseAudio. 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.

; [DecibelFix element] # Decibel fixes can be used to work around missing or incorrect dB
; # information from alsa. 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.
