[Solved] Built-in laptop microphone not working

Hey Arch users, ever since I've installed Arch, it has been running beautifully, but I'm clueless as to how to get my mic to work. I got Audacity, ran it, and it wouldn't record sound. I'm on a Dell Inspiron 1525, using Intel cards.

 $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: INTEL HDMI 0 [INTEL HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 7: STAC92xx Digital [STAC92xx Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Audacity's set to use "default" on playback and recording, apparently recording being set to card 0, which is the only card, and device 0. I alsa tried to record with arecord, and got nothing. Either the kernel (or something else) isn't recognizing my microphone, or I've got some serious configuration to do. I don't know if it's a usb mic, can't tell, so any help would be something. Also, I'm not sure if I should post this here, but when I run audacity from the terminal, I get

Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3653

Is it a bug, or just misconfiguration? I haven't touched any of Audacity's config files, so yeah.

Well, it was simply a matter of firing up alsamixer under normal user, and unmuting everything under Capture.  Yay!
