Tascam UH-7000 losing output in Bit Accurate mode

When using the amp in Bit Accurate mode the sound gets lost very often in Cubase (no signal output). Usually it happens when I play music somewhere outside Cubase, then switch back. The only thing that helps to restore the output is to power off/on the amp.
No such issue in Core Audio mode, though output has big playback latency issue.
Not sure if it’s related to Cubase or Tascam, so reporting to both.

Setup details:
MacBook Pro, mac os 10.12.3
UH-7000 driver version 1.31
Cubase 9 Pro version 9.0.10
