@John Hoff The windows VM is the key. It's the top layer of the 3-layer cake. The middle layer is linux and the bottom layer is the hardware. In linux we record the windows driver communicating with the audio codec in the hardware's firmware with the hope that we can play back the recording in the linux driver.
Comment 19 [1] shows my excitement when I got the VM working. Specifically, I had a windows VM in which I could play audio and hear it in the speakers. I could see the windows driver communication with the audio codec in the VM's IOMMU. I can help you get to this point, which is where I'm stuck.
