Welcome to ASIO4ALL! 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.

In order to achieve the best possible results with ASIO4ALL on a very old computer, it is recommended that your computer is configured accordingly:

• When running an old version of Windows, set the power scheme to “Always On” (XP) or “High Performance” (Vista) in order to turn off Processor P-State switching! Advanced: Modify an existing power scheme so as to not switch CPU speed, because other power settings are not that critical.
• Turn off system sounds! While e.g. the Windows logon sound certainly will not be a problem, sound effects in response to button clicks, notifications etc. will mean that for the time they play, ASIO4ALL may be unable to initialize the audio device.

Note: Fortunately these issues are less important, should you be using a version of Windows that is less than 10 years old! You should not need to re-configure your system, then.
