Hallo liebe Community,
ich bin am verzweifeln.
Seit geraumer Zeit habe ich vor allem beim Spielen, aber z.b. auch beim Windows Startsound keinen klaren Ton mehr.
Es klingt immer mal wieder kratzig, stotternd, rauschend.
Nachdem ich nun dieses Wochenende ein wenig Zeit hatte begab ich mich nun auf Fehlersuche.
LatencyMon zeigte unter anderem einige Treiber als Ursache des Problems an.
Also nutzte ich die Gelegenheit und habe etliche Treiber und mein Bios mal auf den neusten Stand gebracht.
Leider keine Verbesserung. Die selben Verursacher werden weiterhin angezeigt.
Habe mein System aufgeräumt, die Registry gesäubert, Driver Cleaner mal aufräumen lassen.
Keine Besserung. Ich weiß nicht mehr weiter.
Hat jemand von Euch eine Idee?
Vielen Dank schon einmal für die Hilfe.
Hier mal die Ergebnisse die LatencyMon nach einer Runde Witcher 3, Browsen und Musikhören ausspuckt:

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 0:52:47 (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3292 MHz
Measured CPU speed: 1 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.
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): 18707,807214
Average measured interrupt to process latency (µs): 2,970222

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
