Ciao, sto provando a mandare ticket tramite Dell ma non è più abilitato, ho provato a mandare dei messaggi nel forum ufficiale Dell e addirittura il mio post viene segnato come spam.
Detto ciò, senza dilungarmi più di troppo, ho acquistato un Dell Inspiron 7577 a dicembre. Sin dalla prima accensione ha presentato dei grossi problemi all'audio (come avevo anche scritto in questo forum), sono stata in contatto con gli operatori Dell per mesi e mesi, ho spedito il pc in garanzia e non hanno fatto nulla, e per di più non se ne sono mai fregati, ostilità totale, ho perfino richiesto il rimborso (che mi è DOVUTO secondo le norme contrattuali), ma nulla.
Tralasciando questo, di recente ho acquistato una scheda audio esterna (Focusrite Scarlett), pensando di poter risolvere il LORO problema, ed anche perché mi occupo di registrazioni audio, però non ho risolto nulla, anzi. Sono sorti altri problemi, e dopo aver fatto una scansione con LatencyMon è risultato questo (ed è abbastanza grave visto quanto abbia pagato questo pc):

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. 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 0:03:06 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: WINDELL-0VH5V26
OS version: Windows 10 , 10.0, build: 17134 (x64)
Hardware: Inspiron 7577, Dell Inc., 0XCNGT
CPU: GenuineIntel Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
Logical processors: 8
Processor groups: 1
RAM: 16249 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2808 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): 2768,225396
Average measured interrupt to process latency (µs): 5,367890
Highest measured interrupt to DPC latency (µs): 2731,028849
Average measured interrupt to DPC latency (µs): 2,152501

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: supportassistagent.exe

Sembra che i processi a causare problemi siano ACPI.sys e Wdf01000.sys, avete una soluzione su come risolvere o anche in questo caso non riceverò nessuna risposta dal supporto Dell? Grazie.
