Hello guys!
Today I have a new problem that I'm sure we can resolve ..
Windows 10 VM:

- Audio GPU nVidia hdmi: Perfect OK.

- Usb audio with this AUDIO NOISE: https://www.startech.com/it/Schede-adattatori/Audio/Audio-USB/Scheda-audio-USB-esterna~ICUSBAUDIOMH 

 

- Audio with this: Astro A40 -> AUDIO NOISE   http://www.astrogaming.com/headsets/A40-MIXAMP-TR.html 

In your opinion why all USB devices do not work well?

So this is with only the USB device passed through?

If you pass through a USB controller it should work better.

OK thanks. So as I understand it if I buy this, will it work fine? If so it is a problem already solved

I don't know if tat card will pass through. You'll have to search the forum to see what others used.

There isn't a controller on your motherboard you can pass through?

I tried connecting through the motherboard. however, the motherboard is this:

The problem is that I always hear the distorted sound ..

You have to follow this guide to check if you can pass through a whole USB controller to the VM.

I believe I have explained well my problem: my VM passes the USB also, mouse, keyboard and external hard drive work fine! In fact it also works the USB audio device Astro A40, however, he feels distorted and noisy ..
I also have another question: given that use passthrough GPU, I can not use the sound card integrated into the motherboard .. How can I do? Turns out this error (see screenshot)

Passing through a pcie USB card or a USB controller (which I linked you the guide to) will solve your audio problems with your headset.

You could try to set USB mode to 3.0 and see if the audio gets better.

 

The reason why you can't pass through the onboard audio is that there are other devices in the iommu group.

OK thanks ! but can I move to another IMMOU group!

The iommu groups are set by the motherboard maker, but you can try to enable the ACS override in the VM settings to try to force each device I to it's own iommu group.

Thanks for your help!
I just enabled ACS .. what do I do now? how do I proceed?

Reboot and see if the devices are in separate groups.

I've just tried to start Windows 10 VM by entering:
Graphics Card: nVidia GTX 960
Sound Expander Module: Intel integrated
But unfortunately I get this message:

Some idea?

Do a search for getting integrated audio to work on this forum and you'll find your answer. I'm to lazy to search and find the answer for you.

I've tried but I can not separate the two immou group devices. by the time I bought on Amazon 1 controller usb pci-e and an hdmi splitter device. I hope that at least one of the two devices to be able to use my headphones Astro A40!
