Soundcard existing in alsamixer, but not in gnome

Question

I am having the following issue on a Fujitsu laptop with Debian Wheezy:

I have been fiddling around (a little too much) with my sound card, and have finally made it working again, BUT I can only access it using alsamixer (via terminal). That said, the sound card does not show up in the sound-settings in Gnome Classic (it also does not show any icon in the notification-area/bar (next to current battery level)).

So there's no sound-applet and the list from "System Settings"->"Sound"->"Sound cards" is empty, but there is sound!

So I cannot raise/decrease/mute/unmute the sound anywhere else but in alsamixer (not even via keyboard shortcuts).

Here's my sudo aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Here's lspci | grep Audio:

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
        Subsystem: Fujitsu Limited. Device 1475
        Flags: bus master, fast devsel, latency 0, IRQ 44

        Capabilities: <access denied>
        Kernel driver in use: snd_hda_intel

And cat /proc/asound/cards:

 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf2720000 irq 44

Also testing lsmod | grep snd:

soundcore              13065  1 snd

Anyone who has a hunch of why I cannot seem to get Gnome to find the soundcard?
