My problem:

I successfully pass-trough HD 630 IGD from my i5-10400 CPU - asrock H470M-ITX/ac board. I got the video to output on HDMI.I am doing audio passthrough. 00:1f.3 is the audio device I want to passthrough to my Windows,It worked.But it doesn't work after I restart win10.The HDMI still has output.There is no sound on the TV.Unless I restart PVE and then restart win10.
