Disclaimer
This is a fully supported release. While we have tested these drivers extensively, there may still
be bugs lurking. Please be aware that these drivers are used at your own risk; Echo Digital Audio
Corporation is not responsible for any damage or loss incurred by the use of these drivers.
Introduction
This driver supports the following versions of Windows:
•
•
•
•
Windows Vista
Windows Vista 64-bit Edition
Windows 7
Windows 7 64-bit
Copyright © 2009 Echo Digital Audio Corporation. All Rights Reserved.
Windows Vista and Windows 7
This release provides support for Windows Vista and Windows 7 running in 32-bit and 64-bit
mode.
Windows Vista introduced 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 and Windows 7. 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 the latest Windows Vista service pack with this driver.
WaveRT
WaveRT is a new driver model that was introduced with Windows Vista. It is not available with
Windows XP, or earlier releases of Windows. 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 improvements specific to Windows Vista and
Windows 7; 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is no longer available as it has been superseded by Windows Core Audio Exclusive Mode.
Audio application support
Finally, please be aware that not all audio applications have been updated for Windows 7 and
may not behave properly. Some may require you to run them with administrator privileges.
We recommend that you use ASIO mode with Cakewalk’s SONAR.

64-bit Windows
Using Windows in 64-bit mode is very similar to using 32-bit mode. GSIF is not supported in 64bit Windows.
This release includes support for both 32-bit ASIO applications and 64-bit ASIO applications.

The console
This driver release includes a console that has been specifically developed for Windows Vista
and Windows 7. If you are used to the console for previous versions of Windows, this one works
similarly. The main difference is that you select the output using the tabs across the top of the
window.
The new console provides almost all of the same functionality as the previous one, with the
exception of features that are not available with the WaveRT drivers.
You can access the new console from the Start menu in the Echo Digital Audio folder or via the
shortcut on your desktop.
Stereo versus surround sound
Use this control to choose if you want your hardware to show up as multiple stereo pairs or as a
few multichannel wave devices in the Sound control panel.
Synchronize wave devices
Normally, the driver tries to keep playback and recording synchronized. However, there are few
cases where you don't want that. If you are running an application that needs the inputs and
outputs to be totally independent, then turn this off. Most of the time, you probably want to leave
it enabled.
Sample rate display
This area of the Settings page shows the hardware's current sample rate. This will reflect
whatever sample rate has been set by your audio software.
Note that if you set the Core Audio sample rate, the sample rate display will not update until an
audio application begins playing or recording.
System tray icon
When you open the console, you will see an icon added to the system tray. Clicking the left
mouse button on the tray icon will bring all of the console windows to the foreground.
Clicking the right mouse button on the tray icon will display a pop-up menu that will let you select
individual console windows, show or hide all of the console windows, or arrange the console
windows in the middle of your monitor.

Core Audio
Core Audio is the name for the new sound system introduced with Windows Vista.
You can set the sample rate and format used by Core Audio in the Sound control panel. If you
open the Sound control panel, you should see one or more playback and recording devices for
your Echo hardware.
For Echo hardware, each of these playback and recording devices share a common physical
audio clock – in other words, if you have your analog outputs set for 48 kHz, your digital or
headphone outputs are also running at 48 kHz.
However, Core Audio does not recognize this concept. Therefore, rather than setting the Core
Audio sample rate from the Sound control panel, you can set the Core Audio sample rate from
the Echo PCI console.
Be aware that setting the Core Audio sample rate or the digital mode (for products with optical
S/PDIF and ADAT only) from the console will cause the current playback and recording devices
to be removed and new ones created in their place; this ensures that the sample rate is
consistent. The downside is that this will stop any applications that are currently playing or
recording. We therefore recommend that you only change the Core Audio sample rate or the
digital mode when you are not playing or recording.
If you set your audio software to play or record at a different format or sample rate than that
specified for the Core Audio sample rate, Windows will automatically perform format conversion.
Note that none of this applies to audio software that uses ASIO. Setting the Core Audio sample
rate has no effect on the sample rates available to or used by ASIO.

ASIO support
This driver release includes full ASIO 2.2 support. Just select “ASIO Echo PCI” from within your
ASIO-based application.
New features for Windows Vista and Windows 7
The scheduler in Windows Vista and Windows 7 has a new feature called MMCSS, or Multi
Media Class Scheduler Service. MMCSS is intended to enable audio software to run at the
highest priority to avoid glitching.
The ASIO driver included with this release supports MMCSS. On the ASIO control panel, you will
see two new settings.
•
Use multimedia priority boost: Checking this box tells the ASIO driver to use MMCSS to
run at a higher priority.
•
Lower window manager priority: Checking this box causes Windows to prioritize audio
playback and recording over drawing windows on the screen.
Both settings are checked by default.
Finally, the ASIO driver now stores the ASIO control panel settings separately for each individual
user.
I don’t see all of my inputs and outputs.
This is probably due to the fact that another program is using them. The most likely culprit is the
Microsoft wavetable synthesizer, which is being opened by your audio application as a MIDI
output device. Make sure that your audio application does not have “Microsoft GS Wavetable SW
Synth” selected as a MIDI output device.
If your outputs still don’t show up, you may have some other software that’s doing the same thing.

Windows volume controls
Windows volume controls and the console volume controls are now synchronized. This means
that if you adjust the playback volume in the console, those changes will be automatically
reflected in the Windows volume controls and vice versa.
You can also control the playback volume using Windows’ volume controls.
For Mia and Mia MIDI, the Windows volume controls only apply to the analog outputs. To adjust
the playback volume for the digital output, you will need to use the console volume controls.
For the Indigo dj, the Windows volume controls only apply to the headphone output. To adjust
the playback volume for the line output, you will need to use the console volume controls.
Note that Windows Vista and Windows 7 do not support setting playback mutes per channel;
therefore playback mutes in the console will always behave as if they were ganged, regardless of
the gang button setting.

Troubleshooting
If your computer spontaneously reboots on you, you probably have experienced what Microsoft
calls a “bug check”, but what everyone else calls the Blue Screen of Death (BSOD).
The default setting for the BSOD is not to show the BSOD, but to reboot the computer. This isn’t
very helpful for tracking down problems. If you are experiencing blue screens, here’s how you
can help us track it down:
Select Start/Settings/Control Panel/System
Click on “Advanced system settings” in the left column
Click on the “Settings” button under “Startup and Recovery”
Uncheck “Automatically restart”
Set the memory dump to “Small Memory Dump” in the drop down menu under “Write debugging
information”
Now, next time you get a blue screen, look at it. See if the crash occurred in echo3g.sys,
echo24.sys, echondgo.sys or EchoIndigoX.sys; if it did, it may be something we need to fix.
Restart your computer and find the most recent .dmp file – this is the memory dump. It’s located
in a folder called “Minidump” under your main Windows folder.
Zip up this .dmp file and send it to techsupport@echoaudio.com along with a description of how it
happened.
