<div dir="ltr">I converted my Win10 VM over to a full libvirt VM, removing qemu command line args from the XML, and I no longer have functioning HDMI audio. The device shows up in device manager as OK, and it detects my monitor as the speakers, which is also correct, but no audio plays, when and when I attempt to to configure the speakers/test the audio, I get a message that the test tone cannot be played. Does anyone know what I need to tweak to get it working again? I moved off the qemu command args style because a system/libvirt/qemu update a while ago changed how the permissions were working and that broke passthrough for me. I also saw Alex recommend not using qemu command args a while back. Video passthrough IS working.<div> </div><div>Thanks in advance!</div><div> </div><div>My XML is as follows:</div><div> </div><div><pre class="gmail-code gmail-highlight"
