Volume Control for RPi Audio DAC
To the delight of many, the previous issue of Elektor had a high-quality network audio player based on the Raspberry Pi/Volumio combination, which however was not provided with a 'real' volume control. Although it is possible to control the volume via Volumio (what’s in a name), but this method seriously affects the high-end characteristics of the DAC for the worse. That is why we now describe a volume control especially developed for the network audio player.
