Devialet does DSD to PCM conversion in software (DSP), not using the PCM1792 for this. The PCM1792 in the Devialet always gets 192kHz PCM.
Acording to Devialet white paper they convert DSD to PCM 40Bit/384kHz with their MAT.

DSD CORE
The DSD sound format (Direct Stream Digital) was released in 1999 with the introduction of the
SACD (Super Audio Compact Disc).
In the « computer audio » era, it has now become much more accessible. Considered by many
industry leaders as the most analog sounding of digital formats, DSD has gained a solid reputation
over time and has quickly become a reference format for the most demanding of audiophiles.
The conventional PCM format of audio CDs encodes music on 16 bits (65536 levels), 44100
times per second, whereas DSD format encodes music on 1 bit (using only 2 levels: 0 or 1) but
much more frequently: 2.8224 million times per second (DSD64 ou DSD 1x), 5.6448 million
times per second (DSD128 ou DSD 2x) and even 11.2896 times per second (DSD256 ou DSD
4x). The raw bitrate of an audio DSD stream is higher than that of an audio CD and equivalent
to a High Definition PCM stream.
Thus, on a bandwidth point of view, it is technically feasible to carry an audio DSD stream over a
High Definition capable PCM digital input. The entire Expert range is now compatible with the
DoP protocol (DSD over PCM). This new feature is available through the USB input but also on
the digital XLR input (AES/EBU), the TOSLINK optical input and all coaxial digital inputs
(S/PDIF). A completely unique feature.
MAT
DSD Core technology converts the DSD format into Expert internal native PCM 40
bits / 384 kHz format thanks to an optimized algorithm, limiting the amount of computational
operations on the audio stream. Using only 15 bit perfect additions (no multiplication, no storage),
the MAT
algorithm performs a 128 taps, linear phase FIR (Finite Impulse Response) digital
filter ensuring the conversion of the DSD format into internal native PCM format with truly
outstanding performances
