Using Asus x570 MB / OS=Proxmox Hypervisor / must pass thru Usb audio devices
Tested current usb audio devices in a running stand alone PC / Linux Mint. All running aok on the pc ( good to go with the devices ) I loaded splice onto Proxmox Hypervisor / it works but its not suitable as the audio come thru garbled. Super easy to do but not what I needed.
Looking to find correct hardware / build hardware for Hypervisor with an additional PCI-E USB adapter then pass the adapter / usb devices / thru to one VM Linux Mint VM. Maybe Win11 if possible but I think this may be a challenge.
I am a older linux user; but no expert so my skill are limited with the command line syntax. And understanding the lingo. So Most of all Thanks for the support. This is a paradigme shift for me as we are moving our Audio studio to complete Linux. Although I did manage to pass thru my ssd devices so far. My main concerns are: Finding the right adapter that USB & VFIO resets properly, then finding the correct modification or steps to configure Proxmox so we pass thru; Sent Asus Tech support email asking about IOMMU for my MB pointing them to this design too. No response yet.
Passthrough of the entire USB controller instead of single devices or USB ports can be a gamechanger. If you need other USB ports for other things, then that’s difficult. And the board must support this.
Just select the USB controller and hit the checkbox for “all functions”. That’s the best for most devices, incl. SAS, SATA or network controller.
That’s the one we are looking for. I’d try using passthrough on 06:00.1 and/or 06:00:3 first. I’m not sure what the root device is…but I would try 06:00.0 after that.
And that’s native USB hardware and should be appreciated by the guest OS.
At Proxmox hypervisor Gui / Mint VM/ hardware/ added USB device (usb0).
Edit USB device: choices: Splice port, Use Usb Vendor Device ID or Use Usb port, both configure to the audio device correctly but audio is distorted. See “Use mapped Device” but not sure how to config that one?
going to give 06:00.1 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller or 06:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controllerit , a riffle…be back later, thanks
This is what I just did (Focusrite is the audio device) 103 is the VM id
( now inside Proxmox gui under 103vm the usb device= 0 the host is assigned )
( rebooted server and Vm ) Audio is still garbled…So passing thur usb on MB is not just like splice)
(Next Plan install a PCI-e adapter usb card and test audio)
This is what I did

Yahoo…what I found is the Prox GUI gave you the abilty to pass thru the PCI card.
The card was: 0000:04:00
Go to hardware tab of VM add :PCI Device: check raw device: then find the item in the list
Bingo…
If the audio is still distorted, you might want to check the audio settings within your Mint VM as well. Ensure that the correct audio device is selected and that the audio drivers are properly installed. Additionally, you may need to experiment with different USB ports on the host to see if that makes a difference.
