Hi everyone, I have the XDA-2 Gen2 and have it connected to my PC (Win 7 pro) via USB. I am running a Pioneer VSX-1325-K which is basically a VSX-33 clone, after installing the unified drivers I had no problems listening to my flac files. Each time I turned on my PC, stereo and XDA-2 everything was working fine, however after about the 5th time drivers or at least in the "Sound" option of my PC the drivers seem to vanish. I renamed the device driver as per the Emotiva PDF file. My Pioneer device driver is always there but not the Emotiva. If I uninstall via the remove programs/Uninstall feature and then reinstall the unified driver they show up and then the same thing happens all over again, I see them for 5 or 6 uses and then they are not there any longer after that.
Any ideas or suggestions?
Darren

I can't help but just wanted to say I have the same problem on Win 7 64 bit. A reinstall of the driver lasts for a short time then the driver can't be found.

Generally drivers that work for a while and then disappear can be traced to one of two things: 1) Something to do with security. For example, there's something called Driver Signature Enforcement (DSE) - which is a security setting that will prevent unsigned drivers from installing or running. Since our drivers aren't signed, if DSE is turned on, then they won't install and, if it's turned on, they will "break" (they'll still be installed but they won't work right). The catch is that DSE is normally NOT enabled on Windows 7 computers, but some few computer manufacturers enable it by default, and a recent Microsoft update seems to have switched it on for many others. If that's what's happening, you simply need to disable Driver Signature Enforcement and the problem will go away. (You can Google for instructions about how to do that.) It's also possible that some particular antivirus or firewall program is removing or blocking the drivers. If that's the case, you need to find out what's doing it - and stop it. It's also possible that, if you use some sort of automatic driver updater program, it may be replacing our driver with a new "equivalent" driver that doesn't work. (The chip we use is relatively popular, so some program may mis-identify it, and load the wrong driver.) If that's the case, you would need to tell your program to leave our driver alone  2) Something to do with USB cable length. The high speed USB audio interface chip we use in our the XDA-2 is sort of fussy about the length of the USB cable you use to connect it (with cables two meters and under being preferred). If you use different cables, and some are longer than that, you may find that they don't work. You may also find that longer cables work erratically (and, if the computer doesn't "see" the DAC, then it won't load the USB driver for it). The XDA-2 also requires an actual USB 2.0 cable to work reliably (some old printer cables may actually be USB 1.1, and may not work very well.) |

Thanks Keith. Disabling DSE worked for me.

"you simply need to disable Driver Signature Enforcement and the problem will go away"
I don't think this is a reasonable suggestion at all. A bit like saying just turn off your anti virus software. "Since our drivers aren't signed" The solution is for Emotiva to supply a signed driver for their product.
If you could turn off DSE for just the one driver that would be an option but turning off DSE for everything has a good potential for unintended consequences. I have spent days tracking down a windows problem only to find it related to a clunky work around like this.
FWIW

If you have an older system....and you want it to work...just disable driver signature and install it. Your PC won't faint. It'll make it through this! And you'll be getting sweet audio on your PC. |

The problem is you need to do this each time you restart and this is a media PC I use a blue-tooth keyboard on. Because you can't access the advanced boot options with a blue-tooth keyboard I need to track down a usb keyboard every time I reboot. (if I want the USB to work)
It's great that the latest and greatest MS OS does not require drivers but I don't like win 10 and win 7 is a long way from EOL.
It seem like if Emotiva wants to be a manufacturer that has the respect of the public this is the sort of thing that should have been sorted out a long time ago.
Schiit has sorted this out rather than have their customers waste their time on it.

Or better still - get Linux. I've had multiple DACs connected to my Linux box and never even had to look for a driver. |
