Comment 64 for bug 1851518

@gannon1

Mike, I didn't have luck with the exact steps in comment 15, but the wiki written by Conner was very solid. I had to work through a couple small differences on my system, but now I have a working QEMU VM where the realtek hardware is recognized and the speakers actually work! I worked through all errors I encountered with the QemuHDADump progam and it appears to be running as expected. I went into device manager and disabled and then re-enabled the realtek audio device, and during the re-enable it recorded the following writes (along with creating related frame binary files) :
