“USB Audio Class 2.0” (UAC2) support means that at least the basics should work with any operating system that has UAC 2.0 drivers, which is at least current Linux, Windows-10, the iToy operating systems, and probably macOS. Then our driver would enumerate potential ASIO sound cards and provide the basic functionality that is not specific to ASIO - our driver does no longer contain ASIO support, but if the underlying portaudio dll does, then our driver won’t know or care that this is an ASIO card, and there aren’t legal problems or license obligations for us, only for you as the end user.

Source code yourself from, and find the instructions on how to download the ASIO SDK and build your own version of libportaudio_圆4.dll with ASIO and put that into the Psychtoolbox folder, so it gets used by our PsychPortAudio driver instead of the standard portaudio_圆4.dll we ship. The workaround for the ASIO driver would be to download the portaudio Only ASIO is special in that it needs special drivers from the card manufacturer. I think WASAPI should work with any Windows audio device, as it utilizes the same drivers as WDMKS or MME. What are your specific needs? The more specific you are, the more likely somebody can answer your questions.
