The ALSA Loopback option in Audio Config creates a loopback device that enables PCM samples that are being played to be simultaneously read from the device hw:Loopback,1,0. This is meant for things like VU meters, multi-room streaming etc.
moOde includes integrated support for two input capable boards namely the Hifiberry DAC+ ADC which provides an analog input and the Audiophonics 9028/9038 board(s) which provide a digital input. Volume control is also provided for the inputs allowing the devices to act as preamps. The Hifiberry board uses the alsaloop command to route the audio from input to output. The Audiophonics does this routing via a configurable setting in its device driver.
