Introduction
Welcome to ASIO4ALL v2! This manual enables you to make the most of your ASIO4ALL installation,
especially as it comes to the advanced features newly introduced in this Version of ASIO4ALL.
The ASIO4ALL v2 installer should have added two new icons to your desktop, one being a link to this
documentation and another to launch the ASIO4ALL control panel in off-line mode.
Getting Started
Setting up your audio software
In order to make use of ASIO4ALL, you need to configure your audio software accordingly. How you would
do this depends on your particular application. Generally, you would always enter the audio configuration
menu and select ASIO -> ASIO4ALL v2.
There now should be a button to launch the ASIO control panel. How this button is labeled depends on your
particular software. Once you press this button, the ASIO4ALL control panel should appear. Please consult
the manual of your audio software for further assistance, if necessary!
Sometimes, the audio software indeed would not provide an ASIO control panel option. This is the case
Winamp and Foobar 2000, for which ASIO output plugins exist. For configuring ASIO4ALL with
these applications anyway, you can launch the off-line control panel from the desktop. Note that the off-line
control panel launcher works like a mini-ASIO-host of its own and does not reflect the current device status
of any instance of ASIO4ALL that may be open at the same time!
Changes made in the off-line control panel will have an effect only after you restart the audio application.
Settings made in the off-line control panel, however, will have no effect at all for applications that have
been configured with the ASIO4ALL (on-line) control panel launched from inside the audio options dialog
of the application.
Once you made it into the ASIO4ALL control panel, you can now proceed with some basic configuration.

List
This is the list of WDM audio devices found in your system. Highlight the device that you want to make
changes to.
Note: All parameter changes always only apply to the currently highlighted device!
If a device name appears in bold, this device is enabled. In the picture above, the CMI8738/C3DX PCI
Audio Device would be enabled while all others are not.
The current state of each device is shown by a small icon and can be either of these:
“Running” - The device has been successfully started by the audio engine.
“Available” - The device should be available for use in this session but has not been started yet.
“Unavailable” - The device is in use by another process or otherwise unavailable to the current session.
“Beyond Logic” - You get this if the device for some unknown reason refuses to start and/or displays
erratic behavior of any kind. Sometimes, closing and re-opening the control panel may cure the situation,
as may unplugging and re-inserting of USB devices. Sometimes, this can also mean the same as
“Unavailable”, whenever the device does not report its current availability or the lack thereof back to
ASIO4ALL.
Note: If the device list is empty, this means that you do not have a single WDM audio device in your
system. Please check with your audio hardware manufacturer for a WDM driver!
Buffer Size
Use the slider to adjust the ASIO buffer size for the device currently highlighted. Smaller buffer size
means lower latency. Once you hear crackles or audio becomes distorted, you need to increase the buffer
size. ASIO buffer size directly relates to audio latency. Thus, you want to get a rather small value here.
