The Maya22 functioned perfectly, over-riding the poor quality, on-motherboard, audio of my Dell XPS desktop PC. Moreover, it is a device that I have been able to move to a different computer (an H-P gaming desktop) without any issues whatsoever. Its ability to handle microphone, guitar, and line inputs and support headphones is excellent. The DirectWIRE software is extremely flexible, but the users manual is relatively useless because it only describes two input channels, while the software clearly handles four input channels. The only way I was able to get anything to work was by randomly trying scores of combinations until I found the one combination that worked.
