Hey there,
just recently I discovered that the kernel command line "intel_iommu=on" breaks
audio output (glitching/freezing output via laptop speakers, no output at all
via HDMI) for owners of haswell cpu's.
Changing it to "intel_iommu=igfx_off" resolved the issue.
How ever, in order to use PCI passthrough of my NVIDIA Card to VirtualBox, I
need the parameter "intel_immou=on" ?
Is there a way to fix the audio glitching with intel_iommu=on ?
Is there a way to get nvidia pci passthrough to working without intel_iommu=on
(e.g. intel_iommu=igfx_off) ?
Lots of outputs and other users reporting:

Kind regards !
