Windows Vista
This release provides support for Windows Vista running in 32-bit and 64-bit mode.
Windows Vista features a completely new audio architecture. This new architecture affects any
application that uses DirectSound, wave/MME, or the new Vista audio interfaces. Applications
that use ASIO are unaffected by this new architecture and should work as before.
This driver has been specifically designed for Windows Vista. If you have used Echo hardware
on a previous release of Windows, the driver may behave differently than you expect.
Windows Vista Service Pack 1 contains numerous fixes and improvements for audio hardware.
Echo strongly recommends that you use Windows Vista Service Pack 1 with this driver.
WaveRT
WaveRT is a new driver model that is only supported by Windows Vista. Essentially, WaveRT
lets the driver get out of the way, enabling audio applications to connect more directly to the
hardware.
Applications that use standard Windows audio APIs such as DirectSound, wave or the new Core
Audio API should enjoy more robust, glitch-free performance with the new driver.
Surround sound playback
This driver supports surround sound playback and will automatically create multichannel audio
devices depending on the configuration of your hardware. Unlike the Windows XP driver, no
further configuration is required.
ASIO optimizations
The ASIO driver included with this release includes Vista-specific improvements; please refer to
the ASIO section of this document for more information.
Features that are no longer supported
The driver no longer supports surround sound delay management. In addition, PureWave mode
is no longer available as it has been superseded by Vista’s new Exclusive Mode.
Audio application support
Finally, please be aware that not all audio applications have been updated for Windows Vista and
may not behave properly. Some may require you to run them with administrator privileges.
Since WaveRT is a new driver model, Cakewalk’s SONAR may not work correctly in WDM/KS
mode. We recommend that you use ASIO mode in SONAR. Echo is continuing to work with
Cakewalk to improve the situation.
