Alsa / DSD / USB Amanero

I use an AlloUSBridge with the latest version of DietPi connected to a DAC Audio-GD NFB3.
The Amanero USB card is recognized by Roon.
I can play Flac upsampling or native DSD (DOP) but with DSD 64 alsa says :

Status : access: RW_INTERLEAVED | format: S32_LE | subformat: STD | channels: 2 | rate: 176400 (176400/1) | period_size: 3528 | buffer_size: 7056

It’s normal ?
