The problem was that the command
apt-cache --names-only search linux-backports-modules-alsa | cut -f 1 -d ' ' | xargs sudo apt-get remove --purge
did not execute properly. It listed the modules to be removed, then asked for confirmation but for some reason automatically aborted. When I realized this, I just manually removed the listed components, and reinstalled the patch.
Success!
