Alao, also ich bekomme die Latenz nicht in den Griff.
Weder mit Win 7 als auch mit Win 8.1. Das Problem ist, dass ich immer wieder leichte Störgeräusche bekomme. Lade ich Sample oder Audiofile in Ableton 9.1.8 rein, knackst hin und wieder es. Ich habe auch mein System komplett neu aufgesetzt, Treiber installiert, WLAN deaktiviert, Bluetooth deaktiviert. Keine Verbesserung. Ich benutze eine SSD Festplatte, mit i7 4700MQ, 2,4GHz, 8GB RAM.

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 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 0:04:44 (h:mm:ss) on all processors.
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)
Hardware: 20238, LENOVO, INVALID
CPU: GenuineIntel Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Logical processors: 8
Processor groups: 1
RAM: 8108 MB total
CPU SPEED
Reported CPU speed: 2394 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.
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): 3388,644705
Average measured interrupt to process latency (µs): 3,559558
Highest measured interrupt to DPC latency (µs): 181,748359
Average measured interrupt to DPC latency (µs): 1,625401

Highest reported total ISR routine time (%): 0,074458

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): 255,102757
Driver with highest DPC routine execution time: ndis.sys - NDIS 6.20-Treiber, Microsoft Corporation
Highest reported total DPC routine time (%): 0,851589

DPC count (execution time >=4000 µs): 0

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: svchost.exe
Total number of hard pagefaults 8095
Hard pagefault count of hardest hit process: 2186
Highest hard pagefault resolution time (µs): 500552,374687
Total time spent in hard pagefaults (%): 4,967648
Number of processes hit: 24
