Bonjour,
Depuis quelques temps, après la mise à jour du pilote de ma carte son externe (Focusrite Scarlett 2i2 1st gen), quelque chose s'est altéré dans mon ordinateur. De temps en temps, j'ai la sensation que le pilote audio perd contrôle et le son que j'ai est complètement déchiqueté, saccadé jusqu'à ce que je désactive puis réactive le périphérique dans le menu "Périphériques de Lecture". En plus de cela, j'éprouve des micro-coupures parfois intempestives qui peuvent gêner dans mes tâches lié à la MAO. Autre chose qui a peut-être un rapport avec tout ça : mon entrée sur Discord est également saccadé, aussi bien sur sous-moteur Legacy que le normal.
J'ai contacté le support de Focusrite, qui m'ont proposé de diagnostiquer le problème et en trouver l'origine. Avec le logiciel LatencyMon, j'ai pu chercher ce qui posait problème : voici le rapport de LatencyMon.

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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:19:27 (h:mm:ss) on all processors.

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): 5445,539469
Average measured interrupt to process latency (µs): 10,013894
Highest measured interrupt to DPC latency (µs): 5436,453035
Average measured interrupt to DPC latency (µs): 2,723618

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: mcshield.exe
Total number of hard pagefaults 2569
Hard pagefault count of hardest hit process: 768
Number of processes hit: 27
