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.
