PipeWire: Media Session Module: Default Profile

PipeWire 0.4.2

Media Session Module: Default Profile

The default profile module restores a previously saved profile or otherwise the best available profile.

The module tracks the SPA_PARAM_Profile parameter on devices (excluding Bluetooth devices). When the profile is changed by an external party (e.g. `pavucontrol`), that profile is written to the state file. In the future, when the active profile is `"off"`, the previously saved profile (if available) is restored.

If no saved profile exists, the best profile is restored. The rules for determining the best profile are:

- the highest-priority available profile, or, if no profiles are available,
- the highest-priority profile with availability unknown, or, if no such profile exists,
- the `"off"` profile.

Note
  The special profile named `"pro-audio"` is excluded from the above search.

## Module-specific properties

This module stores its state in `$XDG_CONFIG_HOME/pipewire/media-sesssion.d/default-profile`:

- `default.profile.$devicename = { "name": "$profilename" }`: stores the default profile for `$devicename`
