| ; 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 (or name and index | |
| ; # separated by a comma). | |
| ; # | |
| ; # 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. | |
