Hello, answer please three questions:

1. At me through the adapter in a jack of a microphone of a sound card, the 
wire from a telephone line is connected.
Under operational system from Microsoft Windows XP SP2 the sound perfectly 
enters the name, and under operational system FreeBSD 7.0 with drivers of your 
manufacture at record in general that it is not audible.
I have checked up sensitivity of a microphone of a sound card having submitted 
a signal with oscilograf, frequency 1kHertz and pressure 20, 50, 100 mV, and 
the level of loudness by means of program Audacity under to two above described 
OS looked.
The result has surprised me, under UNIX FreeBSD 7.0; 20mv=0.05-0.01; 
50mV=0.150; 100mV=0.3; and under Microsoft Windows XP SP2 20mV=0.2; 
50mV=0.4-0.45; 100mV=0.55-0.6;
Though result and so was we shall feel on hearing and result above the 
described testing it only has confirmed.
Why on the same equipment such difference?

2. How it is possible to increase sensitivity of a microphone on FreeBSD with a 
condition that loudness everywhere stood on a maximum?

3. I has loaded from your server http://www.4front-tech.com/ archive 
oss-freebsd7-v4.0-1015-i386.tbz and unfortunately have not found out there 
initial texts for sound cards, there are only objective already compiled files, 
from where it is possible to take initial texts for sound cards?
