[SOLVED] Cambridge Audio Amplifier Control

[Nutul]

If you specified another user(as it is the modern way of doing it, after the security rework of the PI team) and you create a brand new (as it woun't exist...) /home/pi directory, you'll run into a new pile of problems.
The best way of fixing the problem would be that of replacing all the occurrencies of /home/pi with /home/<your username>. Although it is a quick and dirty fix, this I agree upon.
