An interface to easily edit the restoration/routing rules of PulseAudio.
-
module-stream-restore(using core api) -
module-device-restore(using tdb) -
module-default-device-restore(using file and core api - can be done through other tools) -
module-card-restore(not covered) -
module-device-manager(not covered - isn't used by most distros)
The restoration process works as follows:
To know the values that will be used to route you can use pacmd to
inspect the sinks/sources, and clients.
Example of properties:
pacmd list-clients
properties:
application.name = "application name"
native-protocol.peer = "UNIX socket client"
native-protocol.version = "34"
application.icon_name = "application name"
application.process.id = "99647"
application.process.user = "username"
application.process.host = "identity"
application.process.binary = "application name"
application.language = "en_US.UTF-8"
window.x11.display = ":0"
application.process.machine_id = "2e1f6f08abbe4c8293e832ead34de3ad"
application.process.session_id = "3"
Relies on pulsectl and tdb libraries.
Additional information:
- A sink is an output device (ex: speaker)
- A sink-input is the stream going towards an output device
- A source is an input device (ex: microphone)
- A source-output is the stream that comes out of the input device
- A sink-monitor is a source automatically created with a sink so that you can record it
- A profile is a state of function for a device (ex: output stereo, input mono)
- A client is an application that generates or consume a stream
- Properties can be attached on streams and devices. These can be used for restoration: automatically attaching streams to devices, setting volume, channel map, mute, on devices when connected
