The main focus here was to give the user the ability to toggle the hardware output loopback state available with following driver patch: https://github.com/tiwai/sound/commit/da2a040ee7cfe1dd57d5bec7906cb979c5787a86 Since the state is added to the saved preset file at the end, old versions of this tool can still read the preset file. Furthermore to not lose this new data should the user accidentally or willfully save the preset with an older version of the tool, the save routine was altered to keep any extra data in a possibly present preset output file.
