It's working perfectly!

With module-always-sink loaded  (I guess sink41 is the null sink):

State changed to (dbus.ObjectPath('/org/pulseaudio/core1/sink41'),)
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}
State changed to (dbus.ObjectPath('/org/pulseaudio/core1/sink42'),)
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}
S

With module-always-sink unloaded:

State changed to ()
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUnset',
'interface': 'org.PulseAudio.Core1'}
State changed to (dbus.ObjectPath('/org/pulseaudio/core1/sink53'),)
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}


Exactly as expected!
Thanks a lot, it's solved as far as I'm concerned.

You can set the HDMI card profile to "off" in pavucontrol or with this pactl
command:

pactl set-card-profile alsa_card.pci-_01_00.1 off

module-always-sink will load a null sink when the last sink is going away, so
when you unplug the headphones, I think the default sink will quickly change
from the analog sink to the null sink, and then from the null sink to the
digital sink.

You can unload module-always-sink (pactl unload-module module-always-sink) to
avoid loading the null sink, to test the case where the default sink becomes
momentarily unset.

Yes, I had made a mistake, it's working correctly with the new version of the
patch! Thanks

Now when I disconnect the headset, the fallback is changed to my hdmi card
(sink0) and immediately after to the integrated card without headphone (sink26,
number upgraded each time I connect/disconnect).
Laine doesn't like the two immediate changes of fallback (but the dbus is still
responsive!), but more importantly, maybe there could be a problem if there is
only one card, so it cannot fallback to sink0. Is there a way to deactivate the
hdmi card so I can test that?

Output from python.dbus when disconnected:

State changed to (dbus.ObjectPath('/org/pulseaudio/core1/sink0'),)
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}
State changed to (dbus.ObjectPath('/org/pulseaudio/core1/sink26'),)
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}
State changed to (dbus.UInt32(2),)

The new pactl output also shows that the card profile changed to iec958. If the
UI still says that the analog profile is active, then that's a bug in the UI
code.

The value changes in `pactl` (see new attachment). And it is correctly changed
in Alsa:
[disconnected]
>>>amixer --card=0 cget numid=44,iface=CARD,name='Front Headphone Jack'
numid=44,iface=CARD,name='Front Headphone Jack'
  ; type=BOOLEAN,access=r---,values=1
  : values=off

[connected]
>>>amixer --card=0 cget numid=44,iface=CARD,name='Front Headphone Jack'
numid=44,iface=CARD,name='Front Headphone Jack'
  ; type=BOOLEAN,access=r---,values=1
  : values=on


I will check again, maybe one pulseaudio module was still using the old patch.

Sorry, wrong command. This is the right command:

amixer --card=0 controls | grep Jack

--- Comment #12 from Tanu Kaskinen  ---
You seem to be still running a pulseaudio version with the old patch. The
assertion that crashes was removed in the new patch.

The "pactl list cards" output shows that pulseaudio thinks that the headphones
are still plugged in:

analog-output-headphones: Headphones (priority: 9000, latency offset: 0 usec,
available)

That's why the card profile doesn't get changed any more. If the headphones are
really unplugged, you can check if it's a pulseaudio bug by looking at what
alsa reports. This command will show all jack elements in alsa:

amixer --card=0 | grep Jack

For example, on my laptop the command prints

numid=21,iface=CARD,name='Dock Headphone Jack'
numid=19,iface=CARD,name='Dock Mic Jack'
numid=22,iface=CARD,name='Headphone Jack'
numid=18,iface=CARD,name='Internal Mic Phantom Jack'
numid=17,iface=CARD,name='Mic Jack'
numid=23,iface=CARD,name='SPDIF Phantom Jack'
numid=20,iface=CARD,name='Speaker Phantom Jack'

Out of those "Headphone Jack" is the one that tells the headphone jack status.
To check the status, I can just copy the whole line and use it in this command:

amixer --card=0 cget numid=22,iface=CARD,name='Headphone Jack'

That prints

numid=22,iface=CARD,name='Headphone Jack'
  ; type=BOOLEAN,access=r---,values=1
  : values=on

If the headphones are unplugged, the last line says "values=off" instead.

I also noticed that with the patched pulseaudio, the name of the sink is not
changed when I disconnect the headset, it remains "Built-in Audio Analog
Stereo", with two ports, "Line Out" and "Headphones". Then, after some more
random manipulations, the PA server crashes.

[pulseaudio-tickets] [Bug 99425] Dbus fallback sink not updating and blocking further action

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=99425

--- Comment #5 from getzze  ---
I compiled pulseaudio with the patch but it is not solving the problem. Now the
pulseaudio dbus disconnects when unplugging the headset. Changing Fallback sink
in pavucontrol brings back the bus.

Error I get from Laine:

PortMenu<._forceFallbackDevice/


The line from portMenu.js do not correspond to the vanilla Laine, I use a fork.


I also have a python script using the python-dbus module, that I wrote for
debugging. It continuously prints the answer to the signals `FallbackSink` and
`InterfaceRevision`. Typically:
>>>pulse_properties.Get('org.PulseAudio.Core1', 'FallbackSink', 
>>>reply_handler=handle_fallback_reply)
>>>pulse_properties.Get('org.PulseAudio.Core1', 'InterfaceRevision', 
>>>reply_handler=handle_fallback_reply)

When I disconnect the headset I get:
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/pulseaudio/core1'), 'member': 'FallbackSinkUpdated',
'interface': 'org.PulseAudio.Core1'}
{'sender': None, 'destination': None, 'path':
dbus.ObjectPath('/org/freedesktop/DBus/Local'), 'member': 'Disconnected',
'interface': 'org.freedesktop.DBus.Local'}


Any further call to the bus do not work. And when I restart the python script
again, the bus does not exists. The error I get (only the useful traceback):


 16 else:
 17 bus = dbus.SessionBus()

[pulseaudio-tickets] [Bug 99425] Dbus fallback sink not updating and blocking further action

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=99425

--- Comment #4 from getzze  ---
I could not test the patch yet.
The signal FallbackSinkUnset is emitted indeed (I modified Laine to listen to
it). The only problem is that the pulseaudio dbus becomes broken after... 
The workaround I use is to call `pacmd` to reset the default sink, so
pulseaudio dbus works again. I call:

/usr/bin/pacmd set-default-sink $(/usr/bin/pacmd list-sinks | awk '/* index:/
{print $3}')

So in `pacmd`, a new default sink is defined when I disconnect the headset. But
not in DBus. There is something wrong there also, no?

--- Comment #3 from Tanu Kaskinen  ---
Laine doesn't seem to listen for the FallbackSinkUnset signal, which is emitted
when the default sink becomes unset. But mostly this is a PulseAudio bug. The
dbus interface doesn't handle the case properly where there's no explicitly
configured default sink, and that's the state that pulseaudio goes into when
the configured default sink disappears.

I believe this patch fixes this bug:
https://patchwork.freedesktop.org/patch/109460/

The patch is pretty old already, but today I reminded Arun about it, and
hopefully he'll review it tomorrow so that it can be merged.

I'd like to try to reproduce this, but to get a better idea of how your
hardware looks, could you attach the output of "pactl list" with and without
headphones plugged in?
