If running a particular radio automation (or other) application, check with the application's manufacturer. They will typically test and approve for use AudioScience drivers. The latest driver on our website may not be the latest driver approved for use by an application's manufacturer.
The "Combo" driver will install the Windows WDM and ASIO drivers by default. It will also give you the option of installing the "32-bit Legacy WAVE driver"
The default selections will work for most installation needs. Include the WAVE when an application specifically requires it (check with the software manufacturer if not sure).
If you need the ASIO driver, it will be installed automatically, then use the application's set-up to choose the ASIO devices (and not WAVE or WDM).
