[PATCH 0/2] alsa-tools/hdspmixer: enhance preset save and add hardware ouput loopback buttons

[Jasmin Fazlic <superfassl@gmail.com>]

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.
