DietPi with Allo BossDAC - plays DSD?

I’m using DietPi [159] with Allo Boss as a Roon Bridge [version 1.0 (build 135)]. If I set the playback setting in Roon to DSD over PCM, DSD64 and DSD128 turn green which suggests to me that those formats are supported. However I only hear static when playing a DSD64 file. As soon as I change Playback setting to Convert to PCM, it sounds fine.

Will the Allo BossDAC play DSD?
If so, is there some other configuration I have to set in DietPi?

It does not:
