indicator-sound has disappeared from my panel

[Steve Langasek]

After a recent update in precise, the sound indicator has disappeared from my panel and isn't coming back. indicator-sound is running, but nowhere to be found in the GUI.

Hi Steve,

Are you running ubuntu 2d or 3d ?

[Steve Langasek (vorlon)]

currently using unity 2d.

[Conor Curran (cjcurran)]

There was an update yesterday Steve for unity-2d. Can you try unity3d and see if it appears.
Just trying to narrow this down and point this bug in the right direction. It doesn't belong here.

[Steve Langasek (vorlon)]

It's been a problem since well before yesterday for me. I think the problem occurred right around beta-1, but I can't be sure of the timing. So the bug was not introduced by yesterday's unity-2d upload, nor does it appear to be resolved by that upload.

If you still need me to test unity-3d to compare, I can try to do so a bit later - system in use right now.

[Conor Curran (cjcurran)]

Yeah if you get a chance later Steve please try on 3d. It would be good to know where to direct this bug.

[Conor Curran (cjcurran)]

As asked above I need to know if this bug is specific to 2d ? Please confirm.

[Steve Langasek (vorlon)]

Tested now, and I'm seeing the same behavior with unity 3d. No sign of the sound indicator under the user session, even though it does show up in the lightdm greeter session.

[Conor Curran (cjcurran)]

Steve, can you confirm that all other system indicators are being loaded on the panel without problems => network, user, devices, messaging and datetime indicator.

Secondly can you confirm that /usr/lib/indicators3/7 has a libsound.so present.
if you install the package libindicator3-tools, can you confirm that you can load the indicator-sound with the indicator-loader with :

/usr/lib/libindicator/indicator-loader3 /usr/lib/indicators3/7/libsoundmenu.so

If the indicator shows up then thirdly we need to see if this is panel-service issue

For this can you attach the output of this command here:

dbus-send --print-reply --session --dest=com.canonical.Unity.Panel.Service /com/canonical/Unity/Panel/Service com.canonical.Unity.Panel.Service.Sync > indicators

thanks C.

Yes, these are all visible, as well as the bluetooth indicator.

There's no /usr/lib/indicators3/7/libsound.so. There is a
/usr/lib/indicators3/7/libsoundmenu.so.

This loads me a blank gray window.

Interesting, could you paste the output from the loader process.

i suppose the question is can it find the .so ? It may be just that the icon is missing. If you click on the blank grey window, does anything happen ?

Ah.
$ /usr/lib/libindicator/indicator-loader3 \
      /usr/lib/indicators3/7/libsoundmenu.so

(indicator-loader3:12479): libindicator-WARNING **: Unable to load icon from file 'audio-output-none' because: Failed to open file 'audio-output-none': No such file or directory

I suppose I should have read the output myself ;) Yes, the icon seems to be
missing here, presumably because I have a non-default icon theme (colorful
ones, because I find the grayscale icons unusable on my desktop).

I'm not sure how to work out which theme package is the correct one to
assign this to?

When I click in the window, I get the 'hand' cursor and can move the window.
Nothing else happens.

Steve which theme are you using ?
Surely if you are using a non- standard theme then this is not a Ubuntu bug ?
Could you revert to our default theme (radiance or whatever) and see if this resolves ?

I don't know how to determine this. It's not any of the choices that are
listed currently under gnome-control-center -> Appearance; it may have been
a custom selection (back when GNOME supported custom selections), with a
standard theme and a different icon set.

However, I've selected 'Ambiance' now, and the sound indicator *still*
doesn't appear. Output from indicator-loader3 is now:

$ /usr/lib/libindicator/indicator-loader3
/usr/lib/indicators3/7/libsoundmenu.so

(indicator-loader3:16971): libindicator-WARNING **: IndicatorObject class
does not have an accessible description.

(indicator-loader3:16971): Gtk-CRITICAL **: gtk_widget_realize: assertion
`widget->priv->anchored || GTK_IS_INVISIBLE (widget)' failed
^C
$

And I get the same blank window as before.

Even if selecting a default theme resolved it, this is still most certainly
an Ubuntu bug. The theme I used was packaged in Ubuntu; it was installed by
default in Ubuntu; and I used a GUI included in the default Ubuntu install
to configure it. If this icon theme is to no longer be supported in Ubuntu,
then it should be removed from the default install (saving space on the
Ubuntu CDs and on users systems), and settings should be automatically
migrated for the user on login after upgrade. Certainly, though, it would
be far better if there were a clear way for someone to *fix* this bug by
providing any missing icons as necessary; I would gladly do so myself if I
could make heads or tails of the problem.

Now, that's not to say this is the highest priority bug in Ubuntu. But as a
project, we should own it, because it's of our own making.

[Steve Langasek (vorlon)]

dug into this through dconf, looks like the icon theme I was using was the Human one.

[Conor Curran (cjcurran)]

Steve, do you run Pulse ?
It should work regardless but I'm just wondering why the audio-output-none wants to be loaded.

[Sebastien Bacher (seb128)]

steve could you also run "strace -f /usr/lib/libindicator/indicator-loader3 /usr/lib/indicators3/7/libsoundmenu.so 2>&1 | grep icon" and add the log here?

[Steve Langasek (vorlon)]

Certainly.

Attached.

[Sebastien Bacher (seb128)]

Steve, is that the full log? it stops on "[pid 29582] stat("/usr/s" which is weird

the
[pid 29582] open("/usr/share/icons/ubuntu-mono-dark/index.theme", O_RDONLY <unfinished ...>

same for the cache in that directory ... why are those never loaded?

I wonder if there is something wrong in that directory on your disk or something...

I don't know why the log would have been truncated in the middle like that. I ^C'ed the process to end it, since otherwise it runs forever. Testing, it looks like this is due to stdio buffering, and ^C being handled by grep before the buffer is flushed.

If I instead kill indicator-loader3, I get some more output. See attached.

How do you define "loaded"? The completion of the stat/open syscalls isn't shown because the syscalls are interrupted, so the return is on a separate line that doesn't show up in the grep; I'm not seeing any indication that things are failing, and I can directly open files in that directory with no problems.

The updated trace attached also shows svg files being loaded from disk; perhaps that's the bit that was missing/confusing before..

[Sebastien Bacher (seb128)]

Steve, is that still an issue?

[Steve Langasek (vorlon)]

Yes, the sound indicator *still* never loads for me.

[Lars Karlitski (larsu)]

Hi leolweb. What do you mean by "disabling audio"?
