I've found Event Mode drastically clearer and more open sounding compared to Push Mode, so I've tried just about everything possible to get it working glitch free.

Having the lowest latency possible is important for your audio.
I still get the occasional glitch, so there is obviously a DPC latency issue on the computer, which I can't fix due to the PC being locked down.
Just go in foobar2000 option then in Advanced/Playback/WASAPI check "Attempt to play unsupported stream formats”
Pavlo, OK, you DAC supports 88200. But does your realtek supports 88200? I guess no.
IOW, the generic Windows driver recognizes the hardware capability, but Realtek's own driver intentionally disables one of its output modes.The Realtek driver includes all the EQ and sound effects software, but I'm not sure I need that, so I uninstalled all audio drivers and let Windows install its own driver a 2nd time, and now I have 88.2kHz playback capability.
I did try it to uninstalling the realtek drivers and indeed the default Microsoft driver gives an 88.2 kHz option. However when I use foobar2000 with the wasapi driver to playback a 88.2 kHz file (which it was first refusing todo) my receiver is reporting 96 kHz so it seems like the Microsoft driver is doing a sample rate conversion.
