Comment 9 for bug 1223840

I know this is an old bug but I have the same issue with a new ASRock Z97 Extreme 6 with an i7 4790S. I've reviewed the linked bugzilla report from post #8 and the *fix* to use 'intel_iommu=on,igfx_off' does indeed allow audio to resume but breaks IOMMU as in I can no long pass through my Nvidia GTX 650 card to a KVM guest. As the bugzilla bug is marked WONTFIX due to a firmware issue I wondered where this now stands with the same problem spanning 2 different vendors i.e. ASUS in the original 2013 and my ASRock today?
