DSD support in UPNP when using HAT

Hi.

My system is as follows
Ropieeexl version 2.573 stable
PI3+
HAT Audiophonics I-Sabre ES9028Q2M DAC
MinimServer

Roon can play up to 128 DSD with no problem.

When I play back DSD in UPNP, it is automatically converted to PCM.
It appears to be a conversion on the hardware side of the ES9028Q2M DAC.

Is there a better way?
