Bug Description
Using Saucy Development I noticed the HDMI audio output of the intel graphics stops working if IOMMU is enabled via kernel boot parameter intel_iommu=on. I need the IOMMU to pass an ATI graphics card to a qemu virtual machine.
WORKAROUND: If the IOMMU is disabled, everything works fine.
