[pulseaudio-discuss] Noise when trying to record audio

I'm running Arch Linux and PulseAudio 6.0 on a Dell Latitude laptop. Sound
output works just fine, both headphones and internal speakers. Sound
recording however doesn't work. Initially, all I got was silence when
attempting to record (tried it with Audacity, arecord, parecord and
Skype). Then, I deleted my configuration (~/.config/pulse) and
restarted; now I get some weird form of noise when recording*. This
happens both for the internal and an external mic. I checked pavucontrol
and the device is unmuted.

* Here's a short sample of what Audacity records:

$ arecord -l
