Bug Description

gnome-control-center 1:3.4.2-0ubuntu0.13.1 in precise updates.
In laptop you can't reproduce this issue, cause there have 'Internal Microphone' already.
I find this issue in my PC, there are two jacks in front panel, input and output.

I made an screen-shot for it.

[Impact]
* User can't adjust the volume when open the 'sound setting' first.
* User still could adjust volume when there are no devices.

[Test Case]
* Install system on a PC(don't have input/output devices)and log in to Desktop
* Connect the headphone in front panel
* Open sound settings menu and click Input tab, you will find you can't adjust the volume.
* Remove all input/output devices, you will find that you still could adjust volume.

[Regression Potential]
* Currently no potential regression.

[Other Info]
* It's an high priority issue in OEM project.

I can change the setting when plug micphone before start 'gnome-control-center sound-nua'.
And also I can change it from pavucontrol.

The sound-nua couldn't call the update function to update input_bar.

This patch fix two issue, it resolve this issue, but I'm an newer for gnome-control-center, so mightbe there are better fix for this issue.
After add the input device, I called 'active_input_update', the input_bar could be adjusted.
The second fix is when we plug out the device, the input_bar is still enabled, we need disable it, but the label on input_bar is still the 'Front Microphone'.

Ara,

 I install the 14.04, and find there are use 'unity-control-center sound' for change sound setting.

 First run 'unity-control-center sound', and insert the microphone in front panel, the input bar could be adjusted. But when I plug out the microphone, the input bar is still enabled, and you can change the input level, in next time when you insert microphone again, you will find the input level was the latest change which is we changed without inserting microphone.

 And I found soucecode is similar with gnome-control-center sound-nua, I'll try to made a patch for trusty.

For precise, I made an merge request for it.

  * Add fix-input-device-bar-status.patch (LP: #1285974)
    First enable input bar when an new input device is added, backport from
    unity-control-center.
    Second, disable input bar when there are not input devices.

Thank you for the work, the change seems fine to me and it looks like it should apply to upstream GNOME (the code seems similar in https://git.gnome.org/browse/gnome-control-center/plain/panels/sound/gvc-mixer-dialog.c)

Could you forward the change to them (https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-control-center)

It also looks like you could apply the same fix for the output as well (not sure how frequent it is to get a machine without audio ouput but it looks like it would lead to the same issue)

Thanks for uploading the fix for this bug report to -proposed. However, when reviewing the package in -proposed and the details of this bug report I noticed that the bug description is missing information required for the SRU process. You can find full details at http://wiki.ubuntu.com/StableReleaseUpdates#Procedure but essentially this bug is missing some of the following: a statement of impact, a test case and details regarding the regression potential. Thanks in advance!
