I recently purchased a HiFiBerry DAC+ from Amazon. I received a board with HW 2.3 with the non-gold RCA connectors. I can see that there are pads for the oscillators as seen in the Pro version, however they are unpopulated. See image attached.
Now I was looking to add a phone jack as an additional output on this DAC+, but if I follow the tracks on the phone jack pads, they are unconnected. It looks like they would be going through some IC marked U5 (currently unpopulated).
Everywhere I see the description for the DAC+ stated as it supports a phone jack out of the box, how come my specific board does not support this? I feel a bit let down here.
What's going on?
