Cocktail Audio X50D USB out to Topping D90 MQA DAC

Description Of Issue

Unable to send MQA signal to Topping D90 MQA DAC for full MQA decoding and rendering. Cocktail Audio X50D is my Roon Endpoint and USB out to Topping D90 MQA DAC. Setting MQA setting to Decoder and Renderer and with ‘Enable MQA Core Decoder’ set to ON, X50D will do the full MQA decode and output 176/192kHz PCM to Topping D90 MQA DAC. With ‘Enable MQA Core Decoder’ set to OFF, again output 176/192kHz PCM to Topping D90 MQA DAC.

With MQA decoding capability set to Renderer, and 'Enable MQA Core Decoder" set to ON, X50D will able to send MQA stream to D90 MQA DAC, and it will do the rendering.

My question is: Is it possible to send full MQA signal to Topping D90 MQA DAC via Cocktail Audio X50D (acting as Roon endpoint) and letting D90 do the full decoding and rendering?

NOTE: Playing Tidal MQA on X50D direct and output via USB to Topping D90 MQA DAC, the DAC can detect MQA signal and do the full decoding and rendering.

Post a screen capture of your signal patch. Also, are you doing any DSP? Specifically Speaker Setup Distance or Volume Leveling?

When MQA Capabilities is set as Renderer, and MQA Core Decoder is Enabled:

MQA Capabilities set to No MQA Support and MQA Core Decoder is Enabled

MQA Capabilities Set to Decoder and Renderer, and MQA Core Decoder is Disabled

For the first scenario, the Topping DAC is showing OFS 48Hz (meaning it is rendering). On the last two scenario, the Topping D90 DAC shows signal is PCM 192kHz.

One more scenario:
MQA Capabilities set to Renderer, and MQA Core Decoder is Disabled

Forget to mention that no DSP or others stuff being set.
