Your ADC type should be set to none.

Your DAC type should be either generic or es9023.

Quirks should be set to quirk_none.

sounds easy!

What about those Crystek oscillators?

Crystek Corporation CCHD-957 Standard Clock Oscillators | Mouser

http://www.digikey.com/scripts/DkSea...-957%20crystek

are they mechanically and electrically compatible with the ones installed on AB-1.x?

That is, is it enough to simply replace the clocks and R8 with R11 ?

Are there any possible side-effect?

Was talked about a few days ago:

Though I think the pad placement for the golledge parts lines up ok with the CCHD957 pads.
to which 1audio had this suggestion.

The isolation from floating them may help since crystals are sensitive to vibration.
In summary I think they should fit though bypass/decoupling caps may be obscured so borges made this suggestion:

Wires should be insulated and pushed tight to board/XO so that they don't create a loop antenna.
I think that captures most of the relevant discussion on the topic. Outstanding challenges are having the skills + equip to get the existing XO off if fitting to an existing board. I'm not sure if having the xo on an adapter is going to detract from the advantages of having the crystek xo so I'm still weighing up my options, I do think that playing with different XOs is another advantage of having the modular format but obviously making a pcb layout for a few XO types will end up with other compromises.

The tricky part will be to get the Golledge XOs off, yes. You can do it destructively by drenching the whole XO in solder. The method I use is a tweezer-iron with wide paddles which each cover two pads.

Have you changed the settings about which I and alexlee188 wrote before?
On your screenshot I see something completely different ...
(Read post number #1713)

You must choose the same parameters and save them...

Later, you must reset the AB 1.2 (on backpanel)

Your computer supposed to show only this: Click the image to open in full size.

In Foobar2000
/Library/Configure/Output/ASIO "USE 64-bit ASIO drivers" must be OFF

Were you able to change the WidgetConfig view to the one in the attachment?

Remember to press Reset after Save for changes to take effect.
