Fail at start with "cannot look up address!"

Symptom:

./apply-equalizer.py

load dbus-module into PA

cannot look up address!
cannot look up address!
cannot look up address!

Goes on forever, about one line per second.
Ctrl-C does not kill process.
Manual kill with PID quits.
Running process again -> same failure.
pulseaudio -k then running again -> works

Weird. I am not able to reproduce this. Ideas?

It still appears from time to time (say, once a month). Ubuntu 14.04.

Hi All,

now I do have the same issue and it is not going away,
everything worked fine on initial setup all sym. links were created and worked correctly
2 days ago i had a X crash on LMDE1 Cinnamon and then I just started receiving black screen with only mouse cursor with no sound so as I had such case before I knew that it was some config file corrupted on my profile so I deleted all config files which would be regenerated including the .config/pulse and
.config/apply-equlizer folder and etc.
Cinnamon is back but since than apply-equlizer doesn't work.
Pulse audio recreated its files as well i did also re-activate pulse-equlizer and did apply settings and tick mark EQ Enabled and Keep Settings. Sound via Equalizer works but apply-equlizer doesn't.

logfile is similar starts with a single line for about 2-3 minutes and than fills it in with the error message:
mint@mint:~$ sudo more /tmp/apply-equalizer_mint.log

23 module-dbus-protocol
cannot look up address!
cannot look up address!
cannot look up address!

I also did kill -the the pulseaudio and as well apply-equlizer than start pulseaudio and than apply-equlizer . The symlinks didnt regenerate only the empty folder is there.

I hope you will be able to pinpoint what could be wrong.

Thanks in advance.

[FelixLeo]

I also just did notice in the background of the X I do have another error message which is only there interestingly that /org/pulseaudio/core1 doesn't exist

[nullEuro]

Hmm, do you run apply-equalizer and pulseaudio as the same user? Also I think you should not use "Keep settings" because this will create a new virtual output device and breaks on port changes (should not be related to the error you get though).

[sgourichon]

Happens also on Ubuntu 16.04 . Same workaround pulseaudio -k works. apply-equalizer and pulseaudio aways run as the same user. Not using "keep settings".
