Add save property to Profile and Route params to notify the session
manager that they should be saved. Let the session manager only save
the Profile and Routes with the save flag.
Make pulse-server set the save flag on Profile and Route changes.
The result is that we can make a difference between user requested
changes and automatical changes and only remember the user preferences.
When a port changes availability, first check if we need to perform
a profile switch, if not select the new best port.
Only poll events and set_param can cause a param changed events.
Keep track of all the changes in the param user data and at the
end of the poll/set_param emit one notification for all changed
params.
When the acp-device impl struct is passed to the log func, it is
possible that when this device is removed, another device using acp
is going to crash while logging a message
When we have accurate enough hardware volume, set the software volume to
1.0. Also fixes the issue of going to 0 volume and then staying silent
until we raise the volume above 1.0.
Add the list of possible ports for a device.
Pass the allowed devices in the routes.
Store the active port in the device.
Fixes enumeration of ports on devices with UCM.
Add a READONLY property flag to makr properties READONLY
Set the base_volume and volume_step in the acp device
Send the base volume and step as REAONLY properties. Use these
in pulse layer.
Add HARDWARE flag to mark a property that does some hardware control.
Mark the device volume/mute property as HARDWARE or not.
Use the HARDWARE property in pulse to set the right flags.
libacp is a port and wrapper around the pulseaudio card profile code.
It uses a set of templates for construct a card profile and mixer port
settings. It also has support for UCM when available for the hardware.
