Here's an earlier post on this issue...
The tool mentioned is called "wav gain" and you can find it on the tools section of my web page below.
===================
!! Please use these settings with caution !!
The following registry key/values control the gain on playback and record:
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\Cisco TSP
WaveDBGainRecord (DWORD)
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\Cisco TSP
WaveDBGainPlayback (DWORD)
The values used in the registry represent dB(in hex), with positive for gain and negative for attenuation. (For example: 0xFFFFFFFD = -3dB) Setting the values to zero will disable the gain control completely.
It should be noted that the initial configuration for these settings are should be -10db (0xFFFFFFF6) for playback and +5 (0x00000005) for record by default, so please keep that in mind as you make changes. Additionally, ranges beyond (+-)10-15 can cause distortion, loss of playback, or complete silence.
If you correctly installed the AV-Cisco TSP 1.0.0.24 from the Unity 2.4.5 release, the gain control functionality should be present from the install of the following file versions:
SelsiusNTWave.DLL (3.0.2.3) 3 OCT 2000
AvAudio.SYS (3.0.2.3) 3 OCT 2000
AvAudio32.DLL (2.4.1.1) 6 AUG 1999
I will hand off a utility to Jeff for changing the wavegain realtime as well as a regedit file to simplify setting the registry entries a bit.
