Hi Uwe,
das Problem wurde leider nicht gelöst und tritt wieder auf. Bisher nicht so extrem, aber es tritt auf. Vielleicht kannst du ja hiermit was anfangen:
LG im Voraus,

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs,
clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to
power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:54:56 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the
interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a
usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 2410,10
Average measured interrupt to process latency (µs): 9,458718
Highest measured interrupt to DPC latency (µs): 2403,90
Average measured interrupt to DPC latency (µs): 5,554764

REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest reported total ISR routine time (%): 0,000783
Driver with highest ISR total time: ACPI.sys - ACPI-Treiber für NT, Microsoft Corporation
Total time spent in ISRs (%) 0,001369
ISR count (execution time <250 µs): 86329
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 298
ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0
_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted
until the DPC has finished execution.
Highest DPC routine execution time (µs): 32266,633588
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation
Highest reported total DPC routine time (%): 0,033813

Total time spent in DPCs (%) 0,077572
DPC count (execution time <250 µs): 1204157
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 9579
DPC count (execution time 1000-2000 µs): 37

DPC count (execution time >=4000 µs): 6

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The
process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in
dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 71962
Hard pagefault count of hardest hit process: 7286
Number of processes hit: 103
