No MQA Output with ifi iDSD nano BL

Hi,

i´m using Volumio with RP3 and my iFI iDSD nano BL wich is able to play mqa (magenta LED)
Sadly with my TIDAL Account and Volumio i´m not able to get out an mqa stream out of Volumio.

Volume is fix at 100. Has anyone the correct settings for Volumio in combination with TIDAL Master?

Thank
–>
