I looked at the snd_hda(4) man page and got a bit of help. After I looked at dmesg(8) and checked my nids I set up my headphones and now the system knows the specific type of headphones that I have. I still can't hear the volume, though, and my mixer volume is 100 percent. What do I do? Here's the result of dmesg(8):
Also, what exactly is cad0 and nid?
