I apologize for not being clearer and including a proper reference; by "this patch", I meant https://issues.guix.gnu.org/71246.

Thanks,

The issue with it applying to the new audacity version is that the "lib-ffmpeg-support" folder moved from under "libraries/" to be under "modules/mod-ffmpeg/"; I have simply restored the existing patch and fixed the paths to the files.

I also tried setting the path to the ffmpeg library through the GUI and had it consistently fail for me, and such files still could not be loaded (I have a few screenshots of the error messages). Restoring this patch has restored the ability to load .m4a and other files which depend on ffmpeg to be loaded, and without any special hoops needed to set up ffmpeg through the UI first.
