* - It attempts to swap the profile on the card from that device and returns .
* - Next , it handles network or bluetooth streams that only require their stream to be made the default .
* - Next it deals with port changes so if the stream ' s active port is not the same as the port on the device

* This method is called from the UI when the user selects a previously unselected device .
* - Firstly it queries the stream from the device .
* - It assumes that if the stream is null that it cannot be a bluetooth or network stream ( they never show unless they have valid sinks and sources )
* In the scenario of a NULL stream on the device
* - It fetches the device ' s preferred profile or if NUll the profile with the highest priority on that device .
* - It then caches this device in control - > priv - > cached_desired_input_id so that when the update_source triggered
* from when we attempt to change profile we will know exactly what device to highlight on that stream .
* - It attempts to swap the profile on the card from that device and returns .
* - Next , it handles network or bluetooth streams that only require their stream to be made the default .
* - Next it deals with port changes so if the stream ' s active port is not the same as the port on the device
* it will attempt to change the port on that stream to be same as the device . If this fails it will return .
* - Finally it will set this new stream to be the default stream and emit a signal for the UI confirming the active input device .

*
* Firstly it checks to see if the incoming stream has no ports .
* - If a stream has no ports but has a valid card ID ( bluetooth ) , it will attempt

* - If a stream has no ports and no valid card id , it goes ahead and makes a new
* device ( software / network devices are only detectable at the sink / source level )
* If the stream has ports it will match each port against the stream using match_stream_with_devices ( ) .

gvc-mixer-control: Really fix double-free when setting headset
In a28e23d9006a32c8982ad8bda11fec131c6b36e8, we said:
The callbacks will be called repeatedly, once with data, and later
on with eol == 0. Make sure to only free it when we get the eol call
instead of once we've applied the settings.
Whereas the docs say:
When requesting all of these [instances] at once, the callback will be
called multiple times, once for each object. When the list has been
exhausted, the callback will be called without an information structure
and the eol parameter set to a positive value.
If an error occurs, the callback will be invoked without an information
structure and eol set to a negative value.
So, in all, we need to free our callback data when eol is positive, or
negative. So, when it's not 0.
Seems we got lucky in the original commit because the test machine only
had a single soundcard.

In PulseAudio without ucm , ports will show up with the following names :
2016-01-11 13:03:51 -05:00
Headphones - analog - output - headphones
Headset mic - analog - input - headset - mic ( was : analog - input - microphone - headset )
Jack in mic - in mode - analog - input - headphone - mic ( was : analog - input - microphone )
However , since regular mics also show up as analog - input - microphone ,
we need to check for certain controls on alsa mixer level too , to know
if we deal with a separate mic jack , or a multi - function jack with a
mic - in mode ( also called " headphone mic " ) .
We check for the following names :
Headphone Mic Jack - indicates headphone and mic - in mode share the same jack ,
i e , not two separate jacks . Hardware cannot distinguish between a
headphone and a mic .
Headset Mic Phantom Jack - indicates headset jack where hardware can not
distinguish between headphones and headsets
Headset Mic Jack - indicates headset jack where hardware can distinguish
between headphones and headsets . There is no use popping up a dialog in
this case , unless we already need to do this for the mic - in mode .
2019-12-02 00:55:28 -05:00
From the PA_PROCOTOL_VERSION = 34 , The device_port structure adds 2 members
2020-06-02 06:20:45 -04:00
availability_group and type , with the help of these 2 members , we could
2019-12-02 00:55:28 -05:00
consolidate the port checking and port setting for non - ucm and with - ucm
cases .

mixer-control: set max_volume to PA_VOLUME_NORM if no valid volume
Reproducers:
1. After a fresh install of Ubuntu 20.04, open a gnome-terminal
and press the Tab key, the system will output a bell notification
sound. Open gnome-control-center and check the sound page,
the output volume of 'System Sounds' is at 0, but the notification
sound is still output at max volume.
2. After a fresh install of Ubuntu 20.04, open gnome-control-center
directly, change to the sound page, the output volume of
'System Sounds' is at its max level. Click any 'Alert Sound' button
at the bottom of the page, the sound is output at max volume but
the UI slider for the output volume of 'System Sounds' changes to 0.
The notification sound can however still could be heard at max volume.
After a fresh install of the system, there is no saved entry for
"sink-input-by-media-role:event" in PulseAudio's module-stream-restore,
so libgvc will create a pa_ext_stream_restore_info in the
_pa_ext_stream_restore_read_cb(). When a notification sound stream
is sent to PA, PA will create an entry with name of
"sink-input-by-media-role:event" and save it to the database, but
volume_valid is false until gnome calls pa_ext_stream_restore_write().
So if users open the gnome-control-center before
pa_ext_stream_restore_write() is called, although there is an entry
named "sink-input-by-media-role:event" in the module-stream-restore,
the volume is not valid in that entry, and calling
pa_cvolume_max (&info->volume) will returns 0.
In this case, libgvc reports the max_volume is 0, but in PulseAudio,
the stream/sink-input volume is max (pa_sink_input_new() of the
sink-input.c).
Check if info->volume.channels is 0, which would mean the volume is
not valid in the entry, and set max_volume to PA_VOLUME_NORM like
_pa_ext_stream_restore_read_cb() does in this case.
Below is the PA log about the stream entry without a valid volume:
E: [pulseaudio] module-stream-restore.c: name=sink-input-by-media-role:event
E: [pulseaudio] module-stream-restore.c: device=(null) no
E: [pulseaudio] module-stream-restore.c: channel_map=(invalid)

mixer-control: Don't specify default c_marshaller
Apart from being less code, this actually gives us a tiny performance
improvement. Up until a few years ago, if you pass `NULL` as the
marshaller for a signal, GLib would fall back to
`g_cclosure_marshal_generic` which uses libffi to pack/unpack its
arguments. One could avoid this by specifying a more specific
marshaller which would then be used to immediately pack and unpack into
GValues with the correct type.
Lately however, as a way of optimizing signal emission (which can be
quite expensive), GLib added a possibility to set a `va_marshaller`,
which skips the unnecessary GValue packing and unpacking and just uses a
valist variant.
Since the performance difference is big enough, if the marshaller
argument is NULL, `g_signal_new()` will now check for the simple
marshallers (return type NONE and a single argument) and set both the
generic and the valist marshaller. In other words, less code for us with
behind-the-scenes optimizations.
In case you also want va_marshallers for more complex signals, you can
use `g_signal_set_va_marshaller()`.

mixer-control: Don't specify default c_marshaller
Apart from being less code, this actually gives us a tiny performance
improvement. Up until a few years ago, if you pass `NULL` as the
marshaller for a signal, GLib would fall back to
`g_cclosure_marshal_generic` which uses libffi to pack/unpack its
arguments. One could avoid this by specifying a more specific
marshaller which would then be used to immediately pack and unpack into
GValues with the correct type.
Lately however, as a way of optimizing signal emission (which can be
quite expensive), GLib added a possibility to set a `va_marshaller`,
which skips the unnecessary GValue packing and unpacking and just uses a
valist variant.
Since the performance difference is big enough, if the marshaller
argument is NULL, `g_signal_new()` will now check for the simple
marshallers (return type NONE and a single argument) and set both the
generic and the valist marshaller. In other words, less code for us with
behind-the-scenes optimizations.
In case you also want va_marshallers for more complex signals, you can
use `g_signal_set_va_marshaller()`.
