BTW, in case you aren't already aware of this: wireshark is pretty good at dissecting USB traffic. You can capture it by doing a "modprobe usbmon", after which you'll see a number of usbmonN devices

I have no idea what higher-level utility library functions exist within EDK2 that you might be able to use. Based on skimming through the USB audio spec, at the raw protocol level you would need to

Does the stuff in "MdeModulePkg/Bus/Usb/UsbBusDxe/UsbDesc.c" help? (I don't know how that's exposed, if at all, through UEFI protocols, alas.) I've added Hao and Ray to the address list (IIUC they

What you describe here makes the virtio-sound device the most complex virtio device that OVMF has ever had any interest in. The only driver you can use as an example is VirtioNetDxe. VirtioRngDxe is
