Configuring Raspbian to include sound card support

#Update Raspbian on the SD card to be the latest available.
pi@raspberrypi ~ $ sudo nano /boot/config.txt
#add the following comments
dtoverlay=iqaudio-dacplus

#To remove the standard Raspberry PI audio card, comment out the {dtparam=audio=on} device tree parameter in your /boot/config.txt and reboot.
pi@raspberrypi ~ $ sudo nano /boot/config.txt
# Enable audio (loads snd_bcm2835)
#dtparam=audio=on

#Flush your filesystem changes and reboot the Raspberry Pi
pi@raspberrypi ~ $ sync
pi@raspberrypi ~ $ sudo reboot

#Once restarted SSH into the Pi and check that the audio drivers / card is available to ALSA.
pi@raspberrypi ~ $ aplay -l

#If the IQaudIO board and drivers have been installed correctly you should see something similar to:
pi@iqaudio ~ $ aplay -l

FAQ

1.Can you use the RCA's as inputs?

Yes, you can try to use the RCA as input in theory. but pls put the DAC (PCM5122) in "mute" mode. (But we do not suggest you use the RCA as input, if so, the DAC will be no output.)

2.Does this X400 V3.0 have analog input?

No, when you use X400 v3.0 with Raspberry Pi , there is no analog input, but if you do not use Raspberry Pi, the RCA port can be used as analog input.

3.If you connect a power switch to the board's connector should it be a momentary or latching switch? also, does it shut down the pi or just the dac?

The X400 v3.0 board use the latching switch, the latching switch shut down both the Pi and DAC.
