I finally found and uninstalled Maxxaudio and now the motu audio PCIe works! Also needed to turn off windows updates. Thanks! Glad that helped. You do need Windows Update running, or you won't get any essential updates, but it may try to install MaxxAudio again... If your question has been answered, please mark a post in this thread as the solution .
Hello I just purchased an XPS 8940. I hoped to use my older PCIe audio card that works great in my Precision T 3600 with windows 7 pro. Is there an adapter you can recommend. Thanks
