To bad the OP thinks they have solved their issue and it is truly not solved. They will possibly not return and spend the next year using a crippled machine.
So to all others who stumble upon this thread. ASIO4all is not an ASIO driver, it is a wrapper for WDM mode. It is to only be used when your device has absolutely no drivers available. If your having trouble with supplied drivers, contact your vendor, please don't go the asio4all route unless it is your last choice.
It has been well documented to cause more problems than it fixes and it can behave like malware and hide in dark corners even after you think you un install it.
CakeAlexs said it all! remove asio4all
COMPLETELY. And this need to happen
before you install your Focusrite drivers.
ASIO4all is the root of the problem here, I guarantee it. Go to the hardware forum and you find a thread that is almost the same. You find many.
Also note that I chose the 6i6 over the 2i2 and 2i4 for a few reasons. One of them being they don't come with the mix control software. This is why you have no ASIO panel I guess. For me the ASIO buffers are adjusted in the mix control GUI.
Focusrite support is top notch and they will answer emails in short order during business hours. Matt usually chimes in on these threads too, must be on holidays..
