Ive applied a proper fix, there was a real problem since we were not
passing the value stored in volume which does ignore the reserved bits
properly, Ive also removed the the check for > 127 since it will never
be the case after & 0x7F operation which was initially your idea but
we cannot just remove volume for the reasons stated above.
