This is not serious from DELL ! 5 months, and there no drivers or bios update about this issue !
A PCIe USB-3 Card is not an option for me, coz i'm on a triple SLI GTX-980, no more PCI Slots available...
There some I/O Interferences between USB, PCIe, and maybe Sata... Waiting for a solution !
I did end up buying a USB 3.0 PCI-e card and installed it just now with the internal power adapter connected to the PC power supply. The drivers are all up to date (PC and PCI-e card) and it is windows 8.1 compatible. No Audio! It registers my Audio Interface but will not play any audio or video. No problems seen in the Device Manager. The card reads my memory sticks and external hard drives with no problems. That totally ***! If I can find a USB 2.0 card that works with Windows 8.1 I may try that. In the meantime I will have to suffer through all the stutters. Hopefully an update will arrive soon! As I had mentioned earlier, I am using a Toshiba Qosmio laptop with USB 3.0 without any problems. Both of my Audio Interfaces work on it and I use the Laptop primarily for recording tracks. Mixing and editing I like to do on my desktop (Area 51 R2 64 bit / Window 8.1 / 24 GB RAM) which is why I bought this rig. Well, it was worth a shot...
The PCI-e card that I have installed is a Vantec 4-Port SuperSpeed USB 3.0 PCI-e Host Card (UGT-PC341). Connected to power supply via Molex to eSata to PCI (ATX) power adapters.

That should have worked. Thanks for reporting your findings.
Also troubling that you get "no audio" at all.
From what you say, the "USB Audio Interface" works properly on other machines. I assume some are also running Win8.1-64bit and you are using the same drivers.
The Vantec PCIe USB-3 card works fine with other USB-3 devices on this Area51-R2.
You have a full-blown compatibility problem here. Sure seems to point to Area51-R2 as the problem.
Not a BIOS update, but there is a new Audio driver for the Area51-R2:
I think this might be the driver for the embedded "Sound Card". It was been reported to fix some audio issues some customers were having.
Could it be that a bad driver was not dis-engaging the on-board audio properly or maybe monopolizing too many resources?
Also, something else comes to mind ... have you all (with external USB Audio devices) tried disabling the on-board audio from the BIOS? Try a clean-install of the new driver first, but if still problems ... if the BIOS option is there, might be something to try.
1. Unfortunately, this new driver has nothing to do with our problem.
2. And of course we have already done everything you recommend.
Thanks for the help I really do appreciate your suggestions. Yeah, I tried disabling HD audio from the BIOS and also the update. I also have disabled the unnecessary sound, video and game controllers in Device Manager which I normally do anyway so there is no conflict. I still have the same problems. If I get some time I will attach a video to demonstrate what is happening.
Looks like there is finally a new BIOS for Area51-R2.
Has anyone with an external USB sound-board-device (and the latency issue) tried it?
BIOS Update :
- Not Applicable
- Enhancement Dell diagnostic fan test.
- Implemented Dell Update Package (DUP) BIOS support.
Doesn't see any USB fixe, but i'm going to test this new bios and report back !
