And be careful not to handle nodes created by si-audio-endpoint,
by using a specific property for that.
Also, use Audio/{Source,Sink}/Virtual as the media class of null sinks
created by si-audio-endpoint, it sounds more appropriate.
Fixes#34
When the autoconnect property is not available or false, we must
simply configure the stream in its default channel map and leave it
unconnected.
Fixes pw-cat -p --target=0 ..
There is no real use for groups in our API. Just use the name of
the file as the default group and be done with it...
Storing multiple groups with this API is problematic because it
forces flushing the file to disk multiple times, one for each group,
and it's just more performant if we use a prefix in the keys
to implement some form of logical separation.
This commit also makes the GKeyFile a temporary object. As we
always load the file from the file system in _load()
and we always replace its contents with a new dictionary in _save(),
there is no point in keeping the keyfile's internal data structures
stored in memory.
Save errors are now also propagated to adhere to the programming
practices of GObject
- sanitize printing properties with tostring(), which will properly
convert nil values to the string "nil"
- ensure some properties become empty strings if they are nil
Sometimes the default device node might not exist when reevaluating endpoints
for the first time on startup, so the policy would link endpoints to another
device node. Then, the default device node appears and the policy moves the
endpoints to the default device node while the previous link has not finish its
activation yet. This race condition can cause endpoint links to fail when being
activated. Delaying the reevaluation of endpoint links until the first client
link is created avoids this issue.
Allows relinking client nodes to other devices if the current device has been
removed. This allows audio to keep playing in a different device if a bluetooth
device is disconnected.
The policy scripts can handle now client nodes that want to be linked with other
client nodes. This is needed for nodes created by the Pulse Audio Volume Control
to monitor audio comming from other application client nodes.
Plugin() is confusing because it's not a constructor, it just finds
an existing instance of a plugin object. All other camel-case
functions are constructors in the current lua API.
These don't make much sense here. In the endpoint policy we want
the clients to be linked to the endpoint that matches their role
and never move.
Also, endpoint priorities are useless. If no endpoint matches the
role, then just ignore the client.
