The pa_cmsg_ancil_data structure has two main guards:
'creds_valid', which implies that it holds credentials
information, and 'nfd', which implies it holds file descriptors.
When code paths create a credentials ancillary data structure,
they just set the 'nfd' guard to zero. Typically, the rest of
pa_cmsg_ancil_data fields related to fds are _all_ left
_uninitialized_.
pa_cmsg_ancil_data_close_fds() has broken the above contract:
it accesses the new 'close_fds_on_cleanup' flag, which is related
to file descriptors, without checking the 'nfd == 0' guard first.
Fix this inconsistency.

We ended up dealing with it once in module init, and once more in the
new module callback. Avoiding it in the second case by name seems to be
the cleanest solution (else, we need to store the module index somewhere
in pa_dbusiface_core, which seems about as bad).

Commit ae415b07a07c9fe70714d01c91980edb25d966de ("dbus: Use hooks for
module new and removed events") changed the new module monitoring from
the asynchronous subscription system. Previously handle_load_module()
created the new pa_dbusiface_module object before we got
a notification of the loading of the module, but now we get the
notification already within the pa_module_load() call. That resulted
in a crash, because the module_new_cb() created the
pa_dbusiface_module object before pa_module_load() returned, and then
handle_load_module() would create another pa_dbusiface_module object
for the same module.
This patch removes the pa_dbusiface_module_new() call from
handle_load_module(). module_new_cb() is now responsible for all
pa_dbusiface_module object creations, except the ones that are created
during the initialization of module-dbus-protocol.

The current LFE crossover filter removes low frequencies from the main
channels and puts them into the LFE channel with the wrong amplitude.
It is not known for sure what is the correct relative amplitude (acoustic
measurements are required with real hardware), and changing that might
introduce a new bug, "it clips the LFE channel".
So just disable the feature by default until a better understanding
emerges how it should work. This, essentially, returns the defaults
to their state as of PulseAudio 6.0.
Some more observations:
- Most of available active analog speakers on the market do the
necessary crossover filtering already, and HDMI receivers can be
configured to do that, too, so a crossover filter in PulseAudio is
harmful in these use cases.
- The "laptop with a builtin subwoofer" use case requires manual
configuration anyway because the default crossover frequency (120 Hz) is
wrong for laptop speakers.
- Finally, Windows 10 with a built-in USB audio driver does not synthesize
the LFE channel given a 5.1 card and a stereo audio stream by default.

Rather than entirely ignore streams for which we have automatically
loaded a filter, this makes module-device-manager only avoid rerouting
such streams within their existing filter hierarchy.
If, for example, m-d-m decided to move a stream which is currently
routed to speakers/mic which we requested echo cancellation for, to a
USB headset, the previous logic would disallow such a move even though
it was legitimate.

Let's assume that there are two output ports, and they are on
different profiles:
* Integrated speakers (priority: 10000, available)
* HDMI (priority: 5900, not available)
Then the user plugs in an HDMI monitor with speakers. Since the HDMI
priority is lower than the speaker priority, we don't route to HDMI by
default. However, the user manually switches the profile to use the
HDMI output.
Then the user plugs out the monitor, so we switch back to speakers.
When the monitor is plugged back in, the user needs to manually switch
the audio output again. That should be improved: if the user preferred
to the HDMI output over the speakers, we should remember that and
automatically switch to HDMI whenever it becomes available.
The lack of automatic switching is even worse when the monitor goes to
a sleep mode after some period of inactivity. The monitor audio may
become unavailable, and PulseAudio can't distinguish that from the
case where the monitor is physically unplugged. Even worse, the
monitor may become unavailable for a short while when adjusting the
display parameters (for example, media center software may adjust the
display parameters to match the media that is being played back). In
these cases we clearly should switch automatically back to HDMI when
it becomes available again.
This patch fixes the problem by setting pa_card.preferred_input_port
and pa_card.preferred_output_port when the user changes the card
profile or a port, and switching to the preferred port when it becomes
available.

I will modify module-switch-on-port-available so that it will keep
track of which input and output port the user prefers on the card,
based on the user's profile and port switches. The preference needs
to be saved on disk, for which I will use module-card-restore.
To facilitate communication between the two modules, this patch adds
preferred_input_port and preferred_output_port fields to pa_card, and
a hook for monitoring the variable changes. It would be nice if the
two modules would communicate directly with each other, but
implementing that would be somewhat complicated, so I chose this time
for adding the functionality to the core. In theory some other routing
module might want to manage the new variables instead of
module-switch-on-port-available, but admittedly that's not very likely
to happen...

Trivial refactoring.
|
| |
|
|
|
| |
I'm sure the original intention was to switch the port if the target
port is available on the currently active profile.
|
| |
|
|
|
|
| |
I don't think there's any reason why the same logic that has
previously added to output profile switching shouldn't be used with
input too.

This reverts commit 12a202c510dcacbd2b85fcc1170484eb16fef491.
This is needed for now to avoid a clash in clients using json-glib. The
commit added a call to json_object_get_type() in client code that didn't
exist before, and this breaks some apps like Rhythmbox and Totem. This
will be fixed in the future by possibly dropping json-c as a dep.

pa_sink_input_set_property() takes care of logging, so the logging
code is redundant.
|
| |
|
|
|
|
|
| |
This saves some proplist allocations and a couple of code lines. Also,
logging is better, because the set_property() functions work with
string values, while the update_proplist() functions assume opaque
binary data, and therefore can't log the property values.
|
| |
|
|
|
| |
pa_sink_input_set_property() does everything pa_sink_input_set_name()
does.

pa_sink_input_update_proplist() is inconvenient in many cases, because
it requires allocating a new proplist, even if the goal is to just set
one property. pa_sink_input_update_properties also can't properly log
property changes, because it has to assume that all values are
arbitrary binary data.
This patch adds pa_sink_input_set_property() for setting a string
value for a single property, and pa_sink_input_set_property_arbitrary()
for setting a binary value for a single property.
pa_sink_input_update_properties() is reimplemented as a wrapper around
pa_sink_input_set_property_arbitrary() to centralize logging and
sending change notifications.
(The above mentions only sink input functions for brevity, but the
same changes are implemented for source outputs too.)

device-manager reroutes all streams whenever a new device appears.
When filter-apply has loaded a filter for some stream, the filter
device may not be what device-manager considers the best device for
the stream, which means that when an unrelated device appears,
device-manager may break the filtering that filter-apply had set up.
This patch changes filter-apply so that it saves the filter device
name to the stream proplist when it sets up a filter. device-manager
can then check the proplist when it does rerouting, and skip the
rerouting for streams that have a filter applied to them.
The proplist isn't cleaned up when the stream moves away from the
filter device, so before doing any decisions based on the
filter_device property, it should be checked that the stream is
currently routed to the filter device. It seemed simpler to do it this
way compared to setting up stream move monitoring in filter-apply and
removing the property when the stream moves away from the filter
device.

Before a device is unlinked, the unlink hook is fired, and it's
possible that a routing module tries to move streams to the unlinked
device in that hook, because it doesn't know that the device is being
unlinked. Of course, the unlinking is obvious when the code is in an
unlink hook callback, but it's possible that some other module does
something in the unlink hook that in turn triggers some other hook,
and it's this second hook where the routing module may get confused.
This patch adds an "unlink_requested" flag that is set before the
unlink hook is fired, and moving streams to a device with that flag
set is prevented.
This patch is motivated by seeing module-device-manager moving a
stream to a sink that was being unlinked. It was a complex case where
an alsa card was changing its profile, while an echo-cancel sink was
connected to the old alsa sink. module-always-sink loaded a null sink
in the middle of the profile change, and after a stream had been
rescued to the null sink, module-device-manager decided to move it
back to the old alsa sink that was being unlinked. That move made no
sense, so I came up with this patch.

When autoloaded, module-echo-cancel doesn't support moving the sink
input and source output that it creates, but the move prevention was
implemented by manually requesting module unloading in the middle of
the stream move procedure, rather than by just setting the DONT_MOVE
flags. This patch removes the module unloading code from the moving()
callbacks and adds the DONT_MOVE flags. In addition to saving some
code, this also prevents problems related to trying to move streams
connected to the echo cancel sink or source while the echo cancel sink
or source is in the middle of a move too (a crash will happen in such
situation, as demonstrated in
https://bugs.freedesktop.org/show_bug.cgi?id=93443).

srbchannel needs fd passing. Otherwise we get the following error
for systems without SCM_CREDENTIALS support:
Code should not be reached at pulsecore/pstream-util.c:95,
function pa_pstream_send_tagstruct_with_fds(). Aborting.
[[ The root cause is that we define HAVE_CREDS only if
SCM_CREDENTIALS is defined, but SCM_CREDENTIALS is a Linux-specific
symbol. Thus HAVE_CREDS is always disabled on Solaris.
And since pulse couples the non-portable creds passing support
with the portable fd passing one, through _35_ places where
HAVE_CREDS is used, a real fix needs a PA redesign -- assuming that
latency on Solaris is something people care about. ]]

Now, trigger_roles, ducking_roles and volume can be divided into several groups by slash.
That means each group can be affected by its own volume policy.
If we need to apply ducking volume level differently that is triggered from
each trigger role(s), this feature would be useful for this purpose.
For example, let's assume that tts should take music and video's volume down to 40%
whereas voice_recognition should take those and tts's volume down to 20%.
In this case, the configuration can be written as below.
trigger_roles=tts/voice_recognition ducking_roles=music,video/music,video,tts volume=40%/20%
If one of ducking role is affected by more than two trigger roles simultaneously,
volume of the ducking role will be applied by method of multiplication.
And it works in the same way as before without any slash.
