  dontWrapGApps = true;

  # Replace audacity's wrapper, to:

  # - put it in the right place, it shouldn't be in "$out/audacity"

  # - Put it in the right place; it shouldn't be in "$out/audacity"

  # - Add the ffmpeg dynamic dependency

  # - Use Xwayland by default on Wayland. See https://github.com/audacity/audacity/pull/5977
