UR824 causes constant CPU spikes

Hi,
on my new system, the UR824 causes constant CPU spikes,
( every 15 secs, 14% max )

Is this as expected ( i.e. what You have to pay for using an USB interface ) ??
My other interfaces do not show any measurable CPU usage.

To repro :
Play anything on the windows mediaplayer with the UR as standard soundcard.
Watch the CPU usage in Task Manager or Resource Monitor.

Apparently, this has a longer history.
There was a Microsoft Quick-Fix for Win 7, which solved it completely for some
and only halfed the spikes for others.

That fix can not be installed on Win7 SP1, though …
