pulseaudio-dlna DBUS error

pulseaudio-dlna DBUS error

Postby pmithrandir » Jun 25th, '16, 23:57

Hello,

I'm trying to find a way to send my sound over dlna to my rpi. it's the one who got the connection to the speakers.

I found pulseaudio-dlna which seems promising. (automaticaly adding dlna "output" to pulse audio control panel)

sadly, when I'm starting it, as normal user, I get the following message :
Code: Select all
Échec : Échec lors de l'initialisation du module
06-26 00:47:34 pulseaudio_dlna.pulseaudio                     CRITICAL PulseAudio seems not to be running or PulseAudio dbus module could not be loaded. The application cannot work properly!


It seems that to make it works, we need to be able to execute the following command :
Code: Select all
pactl load-module module-dbus-protocol

which return in my case
Échec : Échec lors de l'initialisation du module


or "20" If I unload the module before.

Would you know what I could do ?
Pierre

Did you also load the module as normal user? And can you please show the output as normal user of
Code: Select all
set | grep -i dbus
ps -ef | grep -i dbus
LC_ALL=C pactl load-module module-dbus-protocol

FWIW, seems this also applies: https://bugs.mageia.org/show_bug.cgi?id=14709

Hello,

I applied all your command line, as normal user. (same as I did for pulseaudio before)

Do you find something relevant ?
I found this bug also, but as it was from 2014 I thought it might be irrelevant now.

You may need to run pulseaudio from a terminal in verbose mode to get some more output why it can't load the module. See http://askubuntu.com/a/202533 for some more details how to do that,
and also try to rename/move away~/.pulse-cookie and ~/.pulse and also ~/.config/pulse and try after logging in and out again.

I'm still trying to kill pulseaudio... not so easy.

I added to /etc/pulse/client.conf these 2 lines, but without success.
Code: Select all
autospawn = no
daemon-binary = /bin/true


Still trying...

What about
Code: Select all
systemctl --user stop pulseaudio
pulseaudio -k

Hello,

I tried... without success
the command execute itself correctly, but pulseaudio is not killed.
I tried to combine both solution, but no success then also.

It's really strange...

Anything usefull ?
It's run as a daemon, but outside of that, I don't know what to get out of it. Neithr on how to resolv the first issue, getting access to dbus protocol for pulseaudio.

Thank you,

Is the dbus module maybe already loaded? What is the output of
Code: Select all
pacmd list-modules
after a clean boot ?

And after executing the pactl load-module dbus, I manage to load it :
Code: Select all
    index: 21
        name: <module-dbus-protocol>
        argument: <>
        used: -1
        load once: yes
        properties:

                module.description = "D-Bus interface"
                module.version = "5.0.0-6.mga5"

Seems to load, but still not accessible...

Hello,

I'm looking the code : https://github.com/masmu/pulseaudio-dln ... dio.py#L76

It seems that it's looking for /run/pulse/dbus-socket

It's not present in mageia, but maybe I can create a link. Would you know where I could find this link ?

Found it !!!

you have to run this 2 queries as root :
Code: Select all
mkdir /run/pulse
ln -s /run/user/500/pulse/dbus-socket /run/pulse/dbus-socket


The url used by the software is not present in mageia... a small ln and it's good.

ok, so 2 more informations :

- this link is removed when I reboot, I have to find a way to automatize it's creation.
- the system display OSMC(my dlna device) but when it tries to send flow, even if no error are displayed, the music doesn't start.

More fun to discover that it seems...

Hello,

It's working now..
No idea why it was failing before. I rebooted my RPI and now everything seems fine.

I have to find a way to link the /run file at startup + to start the pulseaudio-dlna server and everything will be working at each boot I expect.

Thank you for the help.

Hello,

Last question would be...

how can I run this 2 commands when starting...
They are not services, and I'm not familiar with this part of linux.
I think they must run as root, at least the mkdir must.

Code: Select all
mkdir /run/pulse
ln -s /run/user/$UID/pulse/dbus-socket /run/pulse/dbus-socket


Same question to run as user pulseaudio-dlna at each startup but as user this time.

Regards,

You could add it as a droplet via systemd tmpfiles that control which (temporary) directories are automatically created.
See e.g. https://www.freedesktop.org/software/sy ... les.d.html and take a look at the existing ones as an example and then adapt.
