SPC520 USB Mic No Input Sound | (Video Works)

Hi Guys&Gals,

Thanks in advance for anyone who can help me with this!

DISCLAIMER: I'm still a bit of a Arch Scrub so bear with me please..

I've been reading multiple posts and the ASLA Wiki trying to get this Mic to work;
I may have missed something so if someone could help me troubleshoot this, I would be much obliged.

..
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 0471:0334 Philips (or NXP) SPC 520/525NC PC Camera
Bus 001 Device 003: ID 174c:1153 ASMedia Technology Inc. ASM2115 SATA 6Gb/s bridge
..

Picked up fine by the usb bus.
As above Webcam (video) functions fine in Cheese!

Now for troubleshooting the Audio:

I have PulseAudio and ASLA installed (Pulse sits on top of ASLA Correct?)

pacmd list-source-outputs

1 source output(s) available.
    index: 32
	driver: <protocol-native.c>
	flags: DONT_MOVE 
	state: RUNNING
	source: 3 <alsa_input.usb-0471_USB_Video_Camera-02.analog-mono>
	volume: mono: 65536 / 100% / 0.00 dB
	        balance 0.00
	muted: no
	current latency: 0.00 ms
	requested latency: 40.00 ms
	sample spec: float32le 1ch 25Hz
	channel map: mono
	             Mono
	resample method: peaks
	owner module: 13
	client: 34 <GNOME Volume Control Dialog>
...

So I don't believe the mic is muted I've checked this in both ASLA and Pulse..

amixer -c2

Simple mixer control 'Mic',0
  Capabilities: cvolume cvolume-joined cswitch cswitch-joined
  Capture channels: Mono
  Limits: Capture 0 - 65535
  Mono: Capture 65535 [100%] [127.99dB] [on]
Simple mixer control 'Auto Gain Control',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [off]

And Finally I can see the mic in the Gnome sound settings under the input tab its not picking up any input however. 

I'm stumped for Ideas if anyone could lead me in what to try next, That would be awesome!

Thanks in advance,
Du$ty
