Maybe it works in that other system because 18.10 contains some bug fix
that is missing from your first system (that is 18.04).

I think more likely though it's just that your first system physically
isn't maintaining a clean USB connection. If that's a software problem
then this is a kernel bug but it sounds more like a hardware problem to
me:

[ 5937.978117] usb 1-1.4.2: USB disconnect, device number 16

Please try a different USB port, and/or a different machine that is
running 18.04 rather than 18.10.

Title:
  [USB-Audio - Audioengine D3, playback] fails after a while (a second)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  USB DAC stops playing sound after a second.
  I had problem with kernel 4.15. 
  So, I tried upgrading to 4.19 but still issue persists. 
  I think, we might need to add it to sound/usb/quirks.c

  I see following in dmesg

  [ 5937.978117] usb 1-1.4.2: USB disconnect, device number 16
  [ 5955.721597] usb 1-1.4.1: new full-speed USB device number 17 using xhci_hcd

  And lsusb -v has following entry for the device.
