Picobber and resampling.

I had installed volumio 2.296 and i have a Picobber v. 2.1 DAC.
In the playing option (with GUI) i have selected HiFiBerry DAC (Picobber option doesn’t exists).
The sound is good but is this the best choice ?
A problem: Picobber 2.1 support resampling up to 384 but activating oversampling in volumio GUI
i have NO sound at all !! Can somebody help me to understand this behavior ?

Greetings to the whole community.
