Does MIUI offer USB Audio OTG?

Dec 20, 2012
Hi, Cosimo from Italy.
I have a Mi-One S with Miui Rom. :)

First I tried to connect a pendrive with this cable

Micro USB Host OTG Cable

and Host Mode works. :D

Second I tried to connect a standard USB DAC (Stoner Acoustics UD100) reportedly interworking with the many Android-powered devices (like Samsung Galaxy S III)
and does not work. :(

I think USB audio is not enabled via Miui firmware/kernel.
Can you confirm it to me?
Thanks, Cosimo.
