Auricon 2.2 & 4.1 Manual
Topology
The Auricon topology is shown in the diagrams at the end of this manual.
The playback topology consists of a master output level, mute control and peak meter
(Windows XP, Server 2003, ME and NT4 only), and input monitor level and mute controls for
each of the line inputs. To these the kernel mixer adds virtual level and mute controls for wave,
synthesizer and CD outputs.
The record topology consists of a master input level, mute control and peak meter (Windows
XP, Server 2003, ME and NT4 only), line input level controls for each of the physical inputs and
a digital loopback level control and mute.
The digital loopback allows the output of the card to be digitally mixed back into the input. Under
Windows XP, Server 2003 and ME this function is muted when Windows’ Digital Rights
Management detects that protected audio is being played, in accordance with Microsoft’s
specifications.
Note:
Under Windows Vista, the loopback endpoint is disabled by default. See
the section on Windows Vista above for instructions on how to enable it.
The range on the input and output master controls is -96dB to +6dB, while the individual line
controls range from -96dB to 0dB.
To access the playback and record mixer controls on Windows XP, Server 2003 and earlier,
double-click on the loudspeaker symbol at the bottom right hand corner of the screen. On
Windows Vista, right-click on the loudspeaker symbol, select Playback Devices or Recording
Devices, select the desired endpoint, click on Properties, and then click on the Levels tab.
