1. Connect a wire to all pins except SCK

2. Short the 2 pads on the top of the PCB near the SCK pin (this shorts SCK to GND so the chip generates its own SCK signal)

3. On the back side, for all HxL pads, connect the middle pad with the right pad, except for H3L, connect the middle pad with the left pad

4. Connect to your Raspi GPIO:

|DAC|Raspi|

|---|------|

|BCK|Pin 12|

|DIN|Pin 40|

|LCK|Pin 35|

|GND|Pin 6 (or any GND)|

|VIN|Pin 2 (or any 5V)|

5. Edit /boot/config.txt on your Raspi:

comment out `dtparam=audio=on` (put a # in front), add `dtparam=i2s=on` and `dtoverlay=hifiberry-dac`

6. Create /etc/asound.conf:

7. Reboot your raspi!

8. Connect your AUX cable: You will need to use some force to push the AUX cable all the way in. If a gold contact sticks out, its not all the way in yet!

9. Test: speaker-test -c2 -twav -l7
