Hi,
I'm really new to proxmox/linux and virtualization.
I've installed macos and have a wworking gpu passthhough but i have an issue with my Audio Interface ( Scarlett 2i2). When a sound start ( like a notification or a video/music, the sound is horrible, saturated and sizzling.. So i can't use my interface with Logic..
I notice, the icon of audio volume is grey and i can't change him.
So i tried to pass the interface with his ID in Web GUI and trying to pass an entire port but it's not working. I tried to pass the onboard usb controller but it's work too..
I tried to add vfio kernel to the onboard USB 3 controller but same result..
So i don't know what i can do.. Maybe i do something wrong but i don't found an answer for these problems..
Thanks you for reading my post and for your further answer.
