Habe auch mal mein System mit dem Programm getestet, weil auch ich in unregelmäßigen ABständen Soundaussetzer habe.
Habe keinen Screenshot gemacht, aber die "Current Latency" schwankt bei mir recht stark; Minimal sind Werte um die 70µs, Maximalausschläge habe ich bis ~350µs.
Habe daraufhin mal mein System mit Latency Monitor untersucht und folgende Werte erhalten wie auf den Screenshots zu sehen. Den "Conclusion-Text" schreibe ich mal hier rein, vielleicht kann jemand damit was anfangen:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:08:28 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: MUSIK-PC
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)
Hardware: MS-7693, MSI, 970A-G43 (MS-7693)
CPU: AuthenticAMD AMD FX(tm)-8350 Eight-Core Processor
Logical processors: 8
Processor groups: 1

_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 4000,0 MHz
Measured CPU speed: 3103,0 MHz (approx.)
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): 414,194640
Average measured interrupt to process latency (µs): 7,398534
Highest measured interrupt to DPC latency (µs): 244,472114
Average measured interrupt to DPC latency (µs): 2,888597

REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
Highest ISR routine execution time (µs): 97,2360
Driver with highest ISR routine execution time: USBPORT.SYS - USB 1.1 & 2.0-Porttreiber, Microsoft Corporation
Highest reported total ISR routine time (%): 0,082044
Driver with highest ISR total time: hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation
Total time spent in ISRs (%) 0,163061
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): 355,6740
Driver with highest DPC routine execution time: USBPORT.SYS - USB 1.1 & 2.0-Porttreiber, Microsoft Corporation
Highest reported total DPC routine time (%): 1,061995
Driver with highest DPC total execution time: USBPORT.SYS - USB 1.1 & 2.0-Porttreiber, Microsoft Corporation
Total time spent in DPCs (%) 1,381308
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: explorer.exe
Total number of hard pagefaults 437
Hard pagefault count of hardest hit process: 235
Highest hard pagefault resolution time (µs): 5021,6330
Total time spent in hard pagefaults (%): 0,003076
Number of processes hit: 6

Vor allem diese usbports.sys machen offenbar große Probleme, dabei hab ich außer dem Audio-Interface, dem Cubase-Dongle und meiner Maus gar keine USB-Geräte angeschlossen! Also praktisch nur die "Grundausstattung" zum Recorden...
