your PC. This typically happens if there has been no sound card previously 
installed in the PC. Windows XP (prior to Service Pack 1) and Server 2003 by 
default have the loudspeaker symbol turned off. To enable it, go into 

Control 

Panel

, select 

Sounds, Speech and Audio Devices

, then click on 

Sounds and 

Audio Devices

, and finally tick the box marked 

Place volume icon in the task 

bar.

Configuration

There are three configuration settings for the Auricon 4.4, these being 
stereo/mono mode, nominal line level, input topology and input coupling.

The 

mode

 may be configured as either stereo or mono. In mono mode the 

number of input and output channels that Windows sees is doubled.

The nominal line level can be set to +8dBu, +4dBu or 0dBu. In each case the 
clipping level is 16dB above the nominal level.

The 

input coupling

 can be set to either DC or AC (the default is AC). The AC 

coupling corner frequency is approximately 0.1Hz. Note this is applied after 
the analogue amplifiers, so a differential DC offset on the inputs can cause 
premature clipping.

To change the configuration, right-click on the 

My Computer

 icon on the 

desktop (or in the Start menu in the case of XP, Server 2003, Vista, Server 
2008 and 7), select 

Properties

, then click on 

Device Manager

. On Windows 

8 and Server 2012, open the 

Control Panel

, go to 

System and Security 

and 

then 

System

, and open 

Device Manager 

from the link in the left hand pane. 

Open 

Sound, video and game controllers

, then right-click on 

Auricon 4.4

 and 

select 

Properties

. Now click on the 

Configuration

 tab and select the desired 

mode, line level and/or topology. Under Windows XP and Server 2003 it may 
take a minute or so for Windows to reconfigure itself and the screen may 
flicker during this time. Be patient!

Operation on Windows 8, 7, Vista 

and Server 2012, 2008-R2, 2008

The audio subsystem of Windows 8, 7, Vista and corresponding server 
versions has changed substantially from earlier versions of Windows, 
although most applications should continue to work without modification. 
The major differences likely to affect users of the Auricon 4.4 are described 
below.

Audio Endpoints

Key to the new system is the concept of audio endpoints. These are the 
physical audio sources and destinations, such as microphones, speakers and 
line connectors.

Previously, an audio capture device would typically have multiple inputs 
which were combined in a mixer or selector. Under Windows Vista and later, 
each input is represented by its own device, and Windows itself operates 
the card’s selector to route the chosen source to the A/D converter.

In the case of the Auricon 4.4, each of the physical line inputs is represented 
by an endpoint device, and as the hardware has separate A/D converters for 
each one, they can be used simultaneously. There are also virtual endpoint 
devices for the digital loopback sources, although by default these are 
disabled. To enable these sources, right-click on the loudspeaker symbol 
at the bottom right-hand corner of the screen, select Recording Devices, 
right-click anywhere in the window and select Show Disabled Devices. 
Now right-click on the desired Wave Out Mix device and select Enable. This 
source will now appear as one of the available audio recording devices. 
Note that when an application is recording from a loopback endpoint, the 
corresponding line input is unavailable, and vice versa.

Windows has a default playback endpoint and a default recording endpoint, 
which are typically used by applications where the input or output device 
cannot be explicitly chosen. After the Auricon 4.4 driver is installed,
