I've tried cheese and wxCam and both of those record the video fine, but there is no audio in the videos. How can i record a video from my webcam with audio as well?

OSS was the only audio API in Linux up through the 2.4 series of official (kernel.org) Linux kernels. ALSA was added starting with 2.5, and in those versions, Linux kernel authors marked OSS as deprecated. 4Front continued to develop OSS outside the Linux kernel.

Locate the sound device using arecord -L. Then use it in the commandline. The output is very extensive.
This will record 30 seconds of video from my webcam:
$ ffmpeg -f alsa -i plughw:CARD=C525,DEV=0 -f video4linux2 -s 320x240 -i /dev/video0 -t 30 out.mpg
The arecord output on my system is entered below with the audio device I chose to use highlighted in bold. In this case it's plughw:CARD=C525,DEV=0.

A lot of the many devices can be eliminated based on the audio you are trying to capture, such as the surround sound and in my case other HDMI capture devices.

I had a similar problem with cheese (that is, video was fine, but no audio).
I tried out guvcview based on this answer. This didn't work either, but then I remembered something about USB 3 ports not working with devices like webcams sometimes, so I moved it to a USB 2 port.
Everything worked in guvcview just fine then. The webcam appeared as a new audio device ("USB Audio"). guvcview seems like a neat little application, with a lot of options for how to record from the cam.
(I tried cheese again to see if it was purely the USB 3 port as the cause, but it still didn't work.)
