On #guix, lilyp found the culprit:

... an extra "L" character in the patch file:

Fixed with commit 04cd0ece6219fef2f18ee62442a913a02495fb50

Although Audacity 3.1.3 includes FFmpeg in its direct dependencies, it
does not keep a reference to it and cannot find it at runtime.

This is a regression from Audacity 2.4.2.
