Appendix A – Surround Sound Playback and Recording Driver     2

Overview

With firmware revision 6 and driver version 8.0.0.3512, the Digitorc 4 
exposes additional eight-channel input and output subdevices which are 
overlayed onto the existing four stereo channels. Eight-channel audio 
output is mixed with that of the corresponding stereo outputs, while 
captured audio is replicated in both the 8-channel input and the stereo 
inputs. Separate level and mute controls are provided for each format.

The 8-channel output subdevice is defined as a speaker endpoint, 
allowing speaker locations to be assigned for the playback of 7.1, 5.1 and 
quadraphonic surround sound.

Since Windows doesn’t assign locations for multi-channel inputs, the 
8-channel input is simply defined as another line connector.

Requirements

•  Digitorc 4 card with firmware revision 6 or later.
•  Digitorc 4 driver version 8.0.0.3512 or later.
•  Windows Vista or later (the driver doesn’t support surround sound on 

XP).

Setup

The surround sound input and output subdevices are disabled by default, so 
as not to disturb any existing applications expecting to see only four stereo 
inputs and outputs on the card.

To enable them, follow this procedure:

•  Right-click on the loudspeaker symbol in the bottom right and corner of 

the screen and select 

Playback devices

.

•  Right-click on one of the existing devices and tick 

Show disabled devices

A disabled playback device called Speakers (Digitorc 4) should appear.

•  Right-click on this device and select 

Enable

.

•  Repeat this for the recording devices.
