microphone mute icon support

[TienFu Chen]

When we press mic mute key(XF86AudioMicMute, in some HP's notebook, it's Fn+F8), the notification shows sound mute icon, not mic mute icon. To simulate XF86AudioMicMute, you can run "xdotool key XF86AudioMicMute".

My investigation:
In the file: gsd-media-keys-manager.c, there's no icons[] array for mic mute, there're only volume_icons, brightness_icons, kb_backlight_icons. We should add detection functions for mic volume.

Also we need icon files for mic volume. File name should be something like notification-audio-input-microphone-low-zero, notification-audio-input-microphone-high and located in /usr/share/notify-osd/icons/gnome/scalable/status (offered by notify-osd-icons package).

Packages:
unity-settings-daemon_14.04.0+14.04.20140414-0ubuntu1_amd64.deb

Is this fixed in Vivid?

[TienFu Chen (ctf)]

I don't think this is fixed in vivid, as the source file gsd-media-keys-manager.c is same between trusty and vivid.

Status changed to 'Confirmed' because the bug affects multiple users.

Incidentally HWE engineer Wang Hui has also been working on this issue (LP: #1381856), I am linking his branch here as well.

Hi, guys.

 When could we backport to trusty? Thanks!

[Ara Pulido (ara)]

Is this still needed in Trusty?
