Ciao, ho un problema col mio computer che mi sta mandando pazzo. Quando viene riprodotto del suono, è molte volte distorto. Ho capito che è un problema di latenza e quindi ho usato dpc latency e LatencyMon per monitorare la situazione. Vi lascio di seguito i risultati.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:01:50 (h:mm:ss) on all processors.

Computer name: DESKTOP-NPHOROJ

Hardware: ASUSTeK COMPUTER INC., B150M-A
CPU: GenuineIntel Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3192 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): 507,508365
Average measured interrupt to process latency (µs): 5,132493
Highest measured interrupt to DPC latency (µs): 471,578569
Average measured interrupt to DPC latency (µs): 1,861850

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: chrome.exe
Total number of hard pagefaults 165
Hard pagefault count of hardest hit process: 23
Number of processes hit: 27

I problemi principali sembrano essere Wdf01000.sys e dxgkrnl.sys, ma purtroppo non sono riuscito a trovare una soluzione per nessuno dei due. Ho gia provato a disconnettere tutte le periferiche usb connesse al pc ma non ha avuto effetti. Ho anche gia aggiornato manualmente tutti i driver e il bios. Qualcuno sa aiutarmi?
