[Replicant] PROBING AUDIO LINES ON THE i9305 Samsung Galaxy SIII LTE

I am getting too many errors trying to compile this. It would probably
be easier for me to write (a) busybox/toybox script(s) to save and
restore settings using tinyalsa utils.

On an x86_64 pc I ran alsactl from alsa-utils and stored the card
setting. I don't think I will be able to replicate the same file
format/behaviour if I were to write the scripts (unfortunately) ... the
format looks a bit complicated for me to RE. Instead I will probably
create a couple CSVs with the controls and their respective values, one
without dialling and one in-call.
