Sync Delay Only for HDMI connected Samsung TV to Radeon 7900 XTX through Banana

I'm using VM Banana to send and EQ PC audio to 3 devices (A1: ButtKicker/Realtek on motherboard, A2: Samsung Q90T connected via HDMI 2.1 to a Radeon 7900 XTX, A3: Hyper X Cloud Alpha S connected via USB). All 3 connected via WDM, 48kHz across the board, with 256 byte buffer.

A1 and A3 are perfect and no issues, but A2 has a delay, only when going through VM. If I set it as the default device, there's no delay issue. Any thoughts?

The one thing that stands out is that when setting the WDM buffer, A1 and A3 are changed, but A2 (HDMI) is at 1056 for some reason. Thoughts?
