OK, it looks like DAPS doesn't cope so well with DAB or PTAB as input and a (locked) interface as output.
Limiting number of real-time threads in Playback Engine helped slightly, but not really.
I tried both with a MOTU M64 and Dante Virtual Soundcard as output devices.
I guess the alternative, having a bunch of hidden tracks in Pro Tools to route back through HDX is also fine. (Or there a way to patch this directly within I/O setup?)
