Hi

I have the following generic DAC:
ebay.com/itm/Audiophonics-D … 1757929713
As you can see the guide on the link and various web searches has some connecting via the P5 headeronly. Whereas others are using P5 for 5V and various GPIO pins:
volumio-project-t1522.html
(28,29,30,31) <-However the images show P5 only being used

(12, 35, 39, 40)

I have the yellow V.2.0 board. Cany anyone please advise the proper way to connect it to the Pi 1 B.

Hi Jonesy_sa,

You only need the P5 connector on a PI1B.
Connect it as follows:

DAC ---- P5

MLCK — not connected (the PI doesn’t have a master clock, it’s generated on the DAC)
GND ----- PIN 7
DATA ---- PIN 6
LRCK ---- PIN 4
BCK ------ PIN 3

For supplying power i recommend to use a good quality extra linear power supply with 5V / 200mA but you can also connect it to P5

DAC ---- P5

5V ------- PIN 1
GND ---- PIN 8

Thank you. All soldered up and sounding great.

I selected the “Generic I2S” in settings as I could not see the Audiophonis or ES9023 listed. Is this fine?
Also, I am no longer able to control the volume via Volumio; it is stuck at 100%. Why is this?

Hi,
This DAC does not support hardware volume mixer. You have to use software mixer if you want to be able to set the volume.
