Differential drive is very common in modern audio equipment (removes need for negative rail) and the purpose of the transformer is to allow it to work with either single ended or differential input.

I've made the circuit as per the above mentioned schematic (resistor attenuator + audio transformer).
your views regarding that circuit? Will it be able to work long term without damaging arduino or amplifier?
Thank you.
NiHaoMike:
That should work, but you might need to play with the resistor values to get the desired signal level.
