Figured it out. On a whim, I re downloaded the sierra install app, made a new installer iso, and the new vm made with that is 100%. So somehow, either the creation of the installer or the two different installer apps I previously used caused the error. Either way, glad it's fixed now!

sorry, was looking at the configurator (just woke up and not quite awake so I didn't understand the question.) clover boot is rev 2.3k 3579

4.35.0 UnRaid ver 6.2.4

clean install yielded similar results in terms of audio distortion and being running faster than video.... even tried some different kexts that others said made theirs work, still no luck. seems i'm stuck on el cap for a bit until i get this all sorted. After spending days playing with many different variations of GPU drivers and rom pass throughs etc.... I have been able to isolate my audio problem in sierra. It is occurring even before I assign it a gpu (currently gtx760.) So there has to be a problem somewhere in sierra, or clover, or something? I have no idea were to go from here. When I make a new vm, and connect with splashtop, the audio is present (via soundflower,the only listed output) but has distortions in it. After assigning the gtx 760 to the vm, and passing through the rom file to the video card (and updating to newer web driver) the audio/video sync issue is gone, but the audio distortion remains. If I install the HDMI audio kext, it will output over HDMI with the same distortion. If I plug in an external usb digital to analog convertor, same distortion. I've even created a new installer file on the off chance something was corrupt with the one I was previously using. But the problem remains. Maybe i'm overlooking something?

So..... any thoughts?

look and see if the card is used by anyone building hackintoshes. It may not be os x compatible. Also, download DPCImanager, and see what driver/kext is associated with the usb card. Might help to see what it sees.

aaaand moving to an ssd via unsigned devices did not fix the audio which is moving ahead of the video...... hmm.... update- i attempted to use a usb audio interface and it has the same issues. Perhaps something went awry with the install. Going to attempt a new clean install in a day or so.

bingo. Audio works. Has some syncing issues and "glitches/drops." Vm is on an ssd cache drive and didn't have problems before this but i'm going to try moving it to an ssd mounted outside the array and see if that helps (some people have said it does.) THANKS!

In clover there shall be a boot argument that shall enable use of this driver, check nvda_drv=1 EDIT For me I was loosing HDMI sound with nvidia drivers, even if I reinstalled HDMIAudio-1.1.dmg. Back to OSX Default drivers :-) //Peter I am having quite a difficult time getting HDMI audio to work in sierra. It worked in el capitan for me after installing the hdmi audio kext (1.0). Since creating the new sierra vm, i've tried everything I can think of and would appreciate any assistance: smbios is set o 14,2 video card: gtx760 (passes through to vm just fine) tried hdmiAudio 1.0 and 1.1 kexts added in multiple ways to system/library/extensions, library/extensions, manually adding it, using DPCI manager, a standalone kext installer, adding it to efi: clover/....kexts/other & 10.11 (even made a 10.12 to see if that would work). Have tried all the above using nvidia web drivers and OS X drivers. HDMI audio is displayed as an output option but no audio comes through. I know it's not a cable/hardware issue because it still works in the el capitan vm. any help? I don't know of any other options....

I haven't tried Bluetooth, but I did try 2.4GHZ wireless from 15ft, and it just wasn't reliable (even though the specs said it should be fine). I ended up buying a 50ft ACTIVE extension usb cable (to pass it through the walls) from PrimeCables (cdn company that also resells a bunch of monoprice stuff), and USB works great. Only caveat is it couldn't power an external drive. I've bought a powered hub to see if that helps, but haven't received it yet. As for HDMI, I spent hours researching all the options, and in the end went with 50ft PASSIVE HDMI cable. I considered cat6 hdmi, various active hdmi solutions, and ended up going with this cable because it was cheap ($20cdn), and was overwhelmingly positively reviewed. Tested and works without issue! Hope that helps! they make hdmi+usb over ethernet. but it's not cheap. https://jet.com/product/detail/3de56a6b14e44e3e91775521d7b350ae?jcmp=pla:ggl:gen_electronics_a1:electronics_accessories_audio_video_splitters_switches_a1_other:na:PLA_348772140_24231279300_pla-161708547660:na:na:na:2&code=PLA15&ds_c=gen_electronics_a1&ds_cid=&ds_ag=electronics_accessories_audio_video_splitters_switches_a1_other&product_id=3de56a6b14e44e3e91775521d7b350ae&product_partition_id=161708547660&gclid=CKy068rcqdACFdcRgQod_kACVQ&gclsrc=aw.ds http://www.newegg.com/Product/Product.aspx?Item=9SIA1UH4FD7374&ignorebbr=1&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC-_-pla-_-Pro+A%2FV+Extender+%26+Repeater-_-9SIA1UH4FD7374&gclid=CP6VxMfcqdACFYQkgQodCzwB3A&gclsrc=aw.ds I believe that is for use with an independent, non-networked ethernet cable.

Just wanted to thank gridrunner (and everyone else who has contributed along the way.) This is great guide with many helpful tips. I now have a couple Sierra vm's up, each using a separate nvidia card (gtx 760, gt710) with no issues (well, after having a few issues that got resolved with some reading.) OVMF and clover are really much more useful (for me) than seabios for tailoring the system to specific needs.

Does this only work in 6.2? I (sort of) attempted it on 6.1.9 and the vm would only at the guest has not initialize the the display adapter (paraphrased) after creating the new EFI and rebooting. I also could have messed something up (probably.)

I get about 3-5% loss in cpu performance, but I'm also using older business class hardware.
