Ich habe seit letzter Woche einen neuen Surface Laptop 3 und nutze die DJ-Software Native Instruments Traktor 3 zusammen mit dem Hardware DJ Mixer Traktor Kontrol Z2.
Leider kommt es bei der Nutzung der DJ-Software zu Latenz-Problemen: Konkret kommt es bei der Audioausgabe immer wieder zu unschönen Drop-Outs / Clicks / Glitches.
Laut dem Tool LatencyMon werden die Latenzprobleme durch den Prozess/Treiber "Wdf01000.sys" verursacht. Nach kurzer Recherche, scheint dieses ein häufigeres Problem auch bei Nicht-Surface-Geräten zu sein.
Betriebssystem, DJ-Software und Mixer-Firmware sind auf dem aktuellsten Stand.
Was kann ich tun?

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. Also one or more ISR 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 1:22:22 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: X
OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64)
Hardware: Surface Laptop 3, Microsoft Corporation
CPU: GenuineIntel Intel(R) Core(TM) i5-1035G7 CPU @ 1.20GHz
Logical processors: 8
Processor groups: 1
RAM: 15974 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 1498 MHz
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which
reports your actual CPU frequency and temperature.

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): 3663,20
Average measured interrupt to process latency (µs): 6,044184
Highest measured interrupt to DPC latency (µs): 3648,90
Average measured interrupt to DPC latency (µs): 2,430879

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

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.

Driver with highest DPC routine execution time: Wdf01000.sys - Kernelmodustreiber-Frameworklaufzeit, Microsoft Corporation

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: system
Total number of hard pagefaults 41013
Hard pagefault count of hardest hit process: 4564
Number of processes hit: 72
