No audio in W11 VM

Hi,
I have passed through my GPU and my audio hardware as you can see in the image, but I have no sound in my VM, maybe a problem of drivers?
 

Here is my config:

    You may need to do a manual edit to the xml to set mu!tifunction for the card.

    Also a possibility. As you are passing through both the sound of the GPU (which you should when passing through a GPU)  and the motherboard sound device.
    So in windows there will be 2 devices for audio. I assume as you are passing through the motherboard audio is because that is your preference to use that.
    Probably Windows will put the default to be the HDMI sound from your 3070 and the secondary the onboard. So if the sound is going through the Nvidia sound and you dont have speakers in your monitor then that is why. Try switching the defauly audio out to the secondary audio.
    Just a possibility but maybe why.

    @SpaceInvaderOne I actually added the MB audio because that's the only chance I had in previous tests to have audio working. It works, I have the sound on. 
    However, I have now an even worse issue, my GPU is not detected in my VM anymore. I clean reinstalled my VM because I switched my VM drive, everything was working fine and all, I installed my Nvidia drivers. My GPU was detected until (I suspect) I added the MB audio to the VM config, which i forgot because I realised I had no sound, but since then I am unable to see my GPU in my VM. I realised that everytime I change of video/audio in my VM config, the next time I run the VM nothing works as it used to be, even when I revert the changes. I usually keep a copy of my xml config file before any modif, but this time I forgot, and my GPU is gone.
    Do you think you can tell me if you see something wrong in my config please?
