Today i measured the output of 0dB 1KHz wav signal on Pi, Pi+ with SOA
and Picoreplayer and Wandboard Quad with SOA and last CSOS.

I was using for the measurements the same USB DAC (WaveIO-i2s-Buffalo 2)
with the same alsa parameters 40:4:32:1 and with/without alsa-utils with
max. volume set at LMS.

It is always the same ~1,48V.

It is interesting, that i still have impression that, when using
Wandboard, the dynamics and sound level is lower ...

I don't understand...
