8.2.1.3 Multi-Channel Surround playback
When a multi-channel mode has been established for the Aurora (Modes 1M; 2; 3M or 4),
then surround-sound material can be played and distributed to multiple outputs on the
Aurora.
In addition to using an appropriate Channel Mode, the playback software must have an
option for decoding and playing back surround-encoded material. The playback software
should be set up to use the appropriate Aurora playback device. In some cases, the software
will use the Operating System default – please refer to Section 8.2.1.4 for further details.
When multi-channel interleaved material is played, then the audio will be distributed to the
Aurora outputs according to the following scheme:
Channel Name
5.1 Output
7.1 Output
Front Left
1
1
Front Right
2
2
Front Center

8.2.1.4 System Default Audio Device
Some applications do not allow selection of a specific audio playback device. Instead they
utilize whichever audio device has been defined as the system default play device. To use the
desired Aurora output as the system default:
With Windows XP navigate to:
Start > Control Panel > Sounds and Audio Devices > Audio > Sound Playback: Default
Device = Lynx Aurora XX.
With Windows Vista navigate to:
Start > Control Panel > Sound > Playback. Right-Click the desired Aurora output device and
choose “Set as default device”.
8.2.1.5 ASIO Applications
When using an application that supports the ASIO driver standard, one must specify the
Aurora ASIO driver as the appropriate audio device. Once that is established, multiple stereo
input and output devices will be available for use within the application. Please note: the
channel mode selected for the Aurora will determine the type and number of I/O devices
available, but within ASIO they will always be presented as multiple stereo devices, never as
8-channel devices like with WDM.
