It depends on which interface for example my Katana DAC which uses I2S interface only supports 16 and 32-bit word length.
Some high speed USB chipsets only accept 32-bit word length.
The symptom "On 24/192 seems like RPi loose transfer." suggests a hardware issue with the audio device or the interface, or maybe a bottleneck upstream of the Pi for example the NAS.
