The permissions can be changed on a pretty low level in the registry tree, so you could give regular users control permission (right mouse click / Permissions / Users allow Control) on
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Pro Audio" only, which is where the clockrate setting for Pro Audio is located and no other areas will be affected. This solves the authorisation message.
AS said my preference is a clockrate of 448, so after Gordon set his prefered value, I run a .reg file that puts it back to my prefered value
Hi Aleg,
ok, changing the permissions for Pro Audio works well.
So MQn now changes the value from x2710 (=10000) to x27AF (=10159). Whatever this means.
Now I just wonder about your value of x448 (=1096). It is much lower. And you set it by a .reg file. You could set it and withdraw the permission to change it by MQn. Then you only need to set the value once. Am I wrong?
Cheers

You're correct but i'm lazy, I only figured out this permission setting today because you pointed to a problem with it. I'm running server 2012 which has the permission enabled by default so never get the dreaded message.
BTW the 448 setting is not x448 but d448 or x1c0, so even much lower.
Clockrate is "...used by MMCSS to determine the granularity of processor resource scheduling.
... in 100-nanosecond intervals."
MQn is extremely focussed on how the CPU is doing its things, how all memory movements are being done, commands to be used and avoided by the compiler, instruction sets used, the number of loops for/before moving data from memory, order of instructions for get, copy etc. Not your regular focus for development of audio playback, but very effective IMHO.
