Hi all,
I've successfully passed through my GTX 970 and its audio device (see
below).
02:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce
GTX 970] (rev a1) (prog-if 00 [VGA controller])
Kernel driver in use: vfio-pci
02:00.1 Audio device: NVIDIA Corporation GM204 High Definition Audio
Controller (rev a1)
Kernel driver in use: vfio-pci
Unfortunately, there's a *severe audio stutter* that takes place. I'm not
sure what could be the cause. Has anyone else experienced this? I'm using
kernel *4.5.1-1-ARCH*
*Here's my VM setup:*
