The pulseaudio pa_ato* functions set errno and return -1, when the
number cannot be parsed.
Some parts of parsing the profile files (e.g. parse_eld_device) rely on
these functions returning errors when the input is not a number.
The pulseaudio channel map can only hold 32 AUX channels and we reuse
them when we need more. When we find a duplicate channel, map it to the
next AUX channels.
For SPA libraries that we link against elsewhere in the tree, declare a
declare a dependency "foo_dep" for that library that specifies how to
link to it. Then use that dependency in the various targets.
This removes the knowledge of how to link with the library from the
target which can treat it as just another dependency.
In the case of optional libraries (e.g. the journal support lib) we can
then use declare_dependency() to declare an empty dependencies and thus
link them unconditionally in the target.
Just like the latency, move the codecs to the device Route param.
This way, it is easier for the session manager to save and restore
the codecs as part of the Route settings.
This property is exposed on the device Route and forwarded to the
nodes. It then configured the process_latency.ns field, which
influences the reported port latency.
This makes it possible to change the internal port latency on the
sink and source with pavucontrol and tweak the synchronization to
compensate for internal latencies in the device.
When we store the real_volume we get a hardware_volume as stored
in the mixer and a residual software_volume.
When we read the volume from the card, we need to compare this against
the hardware_volume we stored to check if something changed, not
against the real_volume that also contains the leftover software_volume.
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.
These headers are designed for including in the project. So the user doesn't
need to install valgrind-devel and we don't have to worry about whether the
headers are available or not.
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.
spa/plugins/alsa/acp/channelmap.h:466:9: warning: format not a string
literal and no format arguments [-Wformat-security]
466 | pa_snprintf(s, l, _("(invalid)"));
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
