When the Thumb instructions set is used and frame pointers are enabled
(-fno-omit-frame-pointer), r7 can't be used, because it's used for the
frame pointer. Trying to use r7 caused the compilation to fail.
Thanks to Andre McCurdy for suggesting[1] this fix, all I had to do was to
test that it works. The code builds now, and cpu-remap-test also
succeeds.

On the machines with the ucm used, the different input/output devices
often have different pcm stream, so they often belong to different
sources and sinks, this is greatly different from the design of all
devices connected to a codec (without ucm).
For example, on a machine with ucm2 used:
the internal dmic is on source#0
the external mic is on the source#1
the internal spk is on sink#0
the external headphone is on sink#1
Users expect that after plugging the external device, it will become
the active device automatically. The switch-on-port-available could
make it to be the active_port on its own source/sink, but can't make
source/sink to be default_source/sink since the sources/sinks belong
to the same profile (HiFi usually).
If we adjust the source/sink priority according to ucm ports priority,
the device_port.c could handle the default_source/sink changing then.
Usually we set higher priority for external device than internal
device in the ucm.
In order to bring the lowest side effect on the source/sink priority,
I change the ucm priority to units digit first, then add it to the
original priority.

We met a weird situation on a couple of Lenovo machines and at least
on one Dell machine. First we open the gnome-sound-setting, then
suspend and resume the system, after the system resume back, the audio
devices change to dummy, the audio doesn't work anymore. And pacmd
list-cards shows no available sound card.
Through debugging I found after resume, the alsa receives POLLERR
events and it will call unsuspend to recover the pcm, but at that
moment, the device nodes in /dev/snd/ is not accessible, so the
snd_pcm_open() fails and the pulseaudio unload the module-alsa-card.
Here I add retry and pa_msleep if snd_pcm_open fails, I tested it on
all machines which have this problem, pa_msleep(25) is ok for most of
them, there is only one machine which needs to call pa_msleep(25)
twice, so for safety reason, I set the max retry times to 4.

It's possible for mdev to be NULL. In this case, an assert is taken
in pa_alsa_open_mixer_by_name() with debug builds, and a crash with
release builds. However, it's possible to bypass this trouble by taking
the error path if mdev is NULL.

In single profile mode (headphone and speaker use different PCMs),
when headphone is plugged in, pa_device_port_set_available() will call
pa_core_update_default_sink/source() before posting
PA_SUBSCRIPTION_EVENT_CARD|PA_SUBSCRIPTION_EVENT_CHANGE to the gnome.
And pa_core_update_default_sink/source() will post
PA_SUBSCRIPTION_EVENT_SERVER | PA_SUBSCRIPTION_EVENT_CHANGE to the gnome.
So the original event sequence is:
1. PA_SUBSCRIPTION_EVENT_SERVER | PA_SUBSCRIPTION_EVENT_CHANGE
2. PA_SUBSCRIPTION_EVENT_CARD | PA_SUBSCRIPTION_EVENT_CHANGE
In gnome-control-center:
When it receives PA_SUBSCRIPTION_EVENT_SERVER, it will call
req_update_server_info () to update the panel;
When it receives PA_SUBSCRIPTION_EVENT_CARD, it will update
the card information, for example, when the headphone is connected,
it will call gtk_list_store_append() to append the headphone.
Let's use an example to clarify the correct sequence.
Assume we plug in headphone. PA will set the default sink to headphone
from speaker, and hope gnome sound setting "Output Deivce" to highlight to
"headphone". PA should send PA_SUBSCRIPTION_EVENT_CARD firstly to notify
gnome-control-center "headphone" is plugged in. And then it sends
PA_SUBSCRIPTION_EVENT_SERVER to trigger sound setting to highlight
to "headphone".

Previously avoid_resampling was always false unless the sink or source
implementation explicitly configured the variable. The null sink doesn't
explicitly configure it, so it didn't switch the sample rate as
expected when avoid_resampling was enabled.
This change means that also sinks that don't support rate switching can
have avoid_resampling set to true, but I think that's fine, because
pa_sink_reconfigure() doesn't try to do anything if the reconfigure()
callback isn't set.

I spent a little time working through the implementation of
pa_hashmap, and wrote a test suite while doing so. It tests a few
basic edge cases, like saturating all buckets of the hashtable.
In some cases, the I/O connector functionality can be shared
and we cannot determine the proper purpose automatically.
We just know that something was inserted to the jack.
Introduce a group identifier (a simple string - unique
per group) which helps to determine the proper ports
for the application. The user interface may be used
to set the wanted behaviour.

There is some case that multiple ucm devices share an amixer Jack
like "Headphones", "Headset" and "Mic2" share the "Headphone Mic Jack",
When the Jack state is changed, the module-switch-on-port-available
will process them in the order they are in the jack->ucm_devices, and
the last device will decide the final setting.
But usually users put priority for those devices and expect the
final setting is based on the highest priority device if there is no
other policies like manual selection. So here do some change to store
the ucm_devices according to their priority (from low to high).
For example, we have ucm devices definition like below (ucm2):
SectionDevice."Mic2" {
Comment "Headphones Stereo Microphone"
...
Value {
CapturePriority 200
...
}
SectionDevice."Headset" {
Comment "Headset Mono Microphone"
...
Value {
CapturePriority 300
...
}
}
Without this patch, the final setting is based on Mic2, after applying
this patch, the final setting is based on the Headset (with higher
priority than Mic2).

I moved the intvl variable initialization out of the for loop, because
it looked like the variable value is supposed to be remembered between
the iterations. I don't know if the variable declaration (without
initialization) in the beginning of the loop caused the compiler to
touch the variable between iterations, probably not, but I'm pretty sure
that's undefined behaviour.
Other than that maybe-undefined behaviour, these compiler warnings may
be false positives, since the variables are initialized when u->first is
true.
I initialized the three variables in to the same value as what is used
when resetting them when u->first is true. I didn't test these changes,
but they look safe to me.
Prior to commits f899d5f466 and
f62a49b8cf, GNOME's sound settings
overwrote the routing for all entries in the stream-restore database
when selecting a device. Now we prevent that from happening (see the
aforementioned commits), but the old overwritten settings can still be in
the database after updating to PulseAudio 14.0, and they can cause
problems, as documented here:
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/832
We can't distinguish between devices set by GNOME's sound settings
and devices set by the user, so this patch discards all old device
settings, even though that is going to cause PulseAudio to forget routing
settings for many users. This is less bad than keeping the incorrect
routing settings in the database, because it's difficult for users to
figure out how to fix the situation when e.g. speaker test tones go to
the internal speakers no matter what device is selected as the default,
whereas old manual configuration can be restored restored by doing the
manual configuration again. Also, it's probably more common to have at
some point changed the default device in GNOME's sound settings than it
is to have any manual per-stream routing settings.
This is disabled by default, because this causes data loss, but
distributions that use GNOME are recommended to enable this with
the --enable-stream-restore-clear-old-devices (Autotools) or
-Dstream-restore-clear-old-devices=true (Meson) build option.

pa_namereg_is_valid_name() will hit an assertion if the name string is
NULL. Maybe it would make sense to change pa_namereg_is_valid_name() so
that it would return false on NULL, but I didn't want to change the
function semantics at this time.
e->device and e->card can be NULL even when device_valid and card_valid
are set to true if the database contains bad data.
I ran into this crash while developing new code, I haven't seen the
crash in the wild.
Storing the version in the entry struct is pointless. We should always
write entries using the current version. When we encounter older
versions when reading, those need to be converted to the current version
anyway, because all code that uses the entry struct assumes that the
data is stored according to the current version semantics.
We're currently at the first version of the database entries, so
currently there's no version conversion happening. I have a patch that
will increment the entry version, so this is preparation for that.
In case the local UDP port is blocked by a firewall by default, send
an initial timing packet so the connection tracking will accept the
response packages.
Otherwise, the connection will fail with an 'RTSP/1.0 500 Internal
Server Error' after some timeout.
