I turned the volume way down and got somewhat recognizable sound. It
is heavily distorted, and plays only on the left side. There's a lot
of static and it sounds like it's being modulated by a low frequency.
Could it be something like a buffering problem?

I couldn't find a usbquirks.h file, but I found the lines from the
patch in alsa-kernel/usb/quirks-table.h and edited it manually. We've
made progress! I now have sound, but it is mostly static, buzzes, and
squeals.

I know this isn't the place for general tutorials, but I'm wondering

attempting to follow a tutorial for recompiling the kernel

know nothing about patching.
Reinstalling the kernel can be dangerous if you don't know what you're
doing; I'd recommend you patch the separate driver package:
1) Install the linux-headers package;
2) download ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.23.tar.bz2
3) unpack it:
tar xjf alsa-driver-1.0.23.tar.bz2
4) cd alsa-driver-1.0.23/alsa-kernel
5) patch -p1 < /where/you/put/the/patchfile
6) cd ..
7) ./configure
8) make
9) sudo make install-modules
I support the above strongly. Do not recompile your kernel as a whole. It is
like taking the wheels muffler transmission, engine out of your car to change
the air filter and then putting everything back together again. The chances of
your screwing up something are high. And it takes a long time.
Then unload and load the snd-usb-audio module, or reboot.
(This will overwrite the sound module of your current kernel, so they
might get overwritten again if you update the kernel package.)
If you update the kernel, it will install its modules in a different place,
and you will have to do the whole recompillation again, and install them in
the new kernel.
Thus, unless you reinstall your current kernel, the new modules will not get
overwritten but will not be used, as the modules for the new kernel will be
what are used.
