Can't play 24/192 direct to DAC, but can via HQP

using an iMac, with a thunderbolt connected Lacie Drive as the target store. This setup worked flawlessly on 1.1 whether connected to either a chord Mojo or Audeze Deckard, direct, or via HQP.

After 1.2, I can;t play 24/192 to the Mojo (stalls after 10 secs or so), but with HQP as the selected device, it plays just fine.

Puzzled I am.
