[Voyage-linux] Fwd: Fwd: compiling kernel module for Hiface 1 drivers

[Roberto Grossi]

Sure, this is what I get for 44.1, 48, 8.2 and 96 (I could not check the
others), I have verified these frequencies with my Behringer SRC2496. You
are right, the driver transmits 32 bits little endian (S32_LE).
