Strip the alibpref from the device string in the mapping name. This
name is used to generate the node name eventually and we don't want
this random identifier in it.
Fixes#1362
Strip the _alibpref from the device name, it contains a local counter
to identify the ucm card that should remain internal. We set a flag on
the device to notify of this.
Re-add the _alibpref of the local card to the device name if the
device was flagged.
See #1286
The alibpref fallback does not contain the card number but it is
a local counter instead. Just check if it starts with something in
case the alsa library is not patched to return _alibpref.
Use _alibpref to check if a device needs a UCM local config. Mark
the device as such and use this to set the OPEN_UCM property on
the device.
Open the UCM for a card when the device has the property set. Use the
same logic for loading the UCM as the acp code.
See #1251
When we enable a device, the node will be created and its software
volume will be set to 100%. Update the device volume with this as
well so that changing the volume has an effect.
Fixes#1198
This replaces the manual check for "true" and some (inconsistent) return value
of atoi. All those instances now require either "true" or "1" to parse as
true, any other value (including NULL) is boolean false.
Reset the software volume when initializing the device and when the
hardware volume is updated.
The software volume was set to 0 by default and if the session manager
did not change the volume enough to cause a software volume change,
it would remain 0 and there would be silence.
Also improve the debug a little.
See #1160#1167#1164#1049#1117
This reverts commit 09106151d3.
We need the actual name and description of the mapping, not the
profile or else we end up with the full profile description in the
node description instead of the part of the profile that applies to
the device.
When we set the volume on a port, make sure we also set the save flag
so that the flag is put into the volume changed event and the session
manager can save it.
Fixes#995
Remove the soft mute/volume events, add a new method to get the soft
volume and use the volume_changed event to emit the changed soft and
monitor (real) volumes event for the node.
Make sure the monitor ports always uses the monitor volume, which is the
real volume unaffected by the mixer volumes.
This configures the soft and real volume on the sink/source in all
cases and makes the monitor port follow the real volume of the sink.
See #897
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.
The Pro Audio profile exposes all devices and subdevices with maximum
channel count and no channel layout. It also have no hardware volume
and is more suited for Pro Audio usage.
See #731#704#57
Disable automatic port configuration in acp and move the logic
to the session manager.
Implement initial port selection and restore on profile activation.
Implement route switch when unavailable
Implement port settings save.
UCM profiles can use the same ports, but with different priorities. One
good example is a phone, having an earpiece and a speaker:
- the default profile will put a higher priority on the speaker
- the "voice call" profile will put a higher priority on the earpiece
When switching to the "voice call" profile, we want pipewire to take
into account the priority change, so that the earpiece gets the highest
priority and is selected by default.
As the ports have the same name in both profiles, we have a single
instance of each port in memory, and therefore need to trigger a port
update when the profile is changed, so that the priority set by the new
profile is used.
Moreover, the UCM code updates only the priority inside the
`pa_device_port` structure, so this commit also makes sure we reflect
this value into the `acp_port` structure when enabling a device.
The codepath `pa_alsa_ucm_add_ports` -> `probe_volumes` ->
`pa_alsa_path_probe` was never called leading to no HW volume being set
up when loading a card through UCM. PulseAudio calls this from
`card_set_profile` -> `pa_alsa_{sink,source}_new`.
When a port is plugged/unplugged, first update all the profile states
and then emit a profile change only for the current profile. This way
the device can look at all the updated profiles to select the best one.
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.
