Alberto.
These days sampling rates derived from 44100 are poorly supported.   All the
modern soundcards are based on 48kHz sampling, with all values derived from
that value.   Can I suggest you use this as your base for Argo 2 rather than
22050.

This explains why 11025 is never achieved now, and always ends up at
11100.   I'm not sure why 8000Hz reqested now is not actually 8kHz, is used
to be 8100 presumably because cards back then were 44100 based which can't
give 8000 directly, but from 48kHz they should now - and still don't.
