Résoudre probleme de latence et real time audio

[Patros92]

Bonjour,
Mon pc HP ENVY win 10 ; est très lent et subit des buffers. J'ai mis à jour les pilotes mais rien n'y fait.
Ci-dessous le message de latency monitor qui indique des pbs avec des fichiers syst windows : ndis et storport. cf le rapport ci-dessous.
Que faire ensuite ? Merci de votre aide Positivement

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 0:01:54 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: HPENVY15
OS version: Windows 10 , 10.0, build: 18363 (x64)
Hardware: HP ENVY Notebook, HP, 80E5
CPU: GenuineIntel Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz
Logical processors: 4
Processor groups: 1
RAM: 16266 MB total


_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2592 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): 106248,833333
Average measured interrupt to process latency (µs): 53,900291

Highest measured interrupt to DPC latency (µs): 106182,458333
Average measured interrupt to DPC latency (µs): 25,046486


_________________________________________________________________________________________________________
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): 307,756944
Driver with highest ISR routine execution time: Wdf01000.sys - Runtime de l’infrastructure de pilotes en mode noyau, Microsoft Corporation

Highest reported total ISR routine time (%): 0,021556
Driver with highest ISR total time: Wdf01000.sys - Runtime de l’infrastructure de pilotes en mode noyau, Microsoft Corporation

Total time spent in ISRs (%) 0,024417

ISR count (execution time <250 µs): 4357
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 20
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
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): 106222,050154
Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

Highest reported total DPC routine time (%): 1,124663
Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

Total time spent in DPCs (%) 1,503306

DPC count (execution time <250 µs): 91400
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 33
DPC count (execution time 1000-1999 µs): 1
DPC count (execution time 2000-3999 µs): 0
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: searchprotocolhost.exe

Total number of hard pagefaults 49
Hard pagefault count of hardest hit process: 16
Number of processes hit: 6

Bonjour,

Vérifie la température de l'ordinateur

et :

Suis le tutoriel FRST. ( prends le temps de lire attentivement - tout y est bien expliqué ).

Attendre la fin du scan, un message indique que l'analyse est terminée.
Télécharge et lance le scan FRST,

Trois rapports FRST seront générés :
* FRST.txt
* Shortcut.
* Additionnal.txt

Envoie ces 3 rapports sur le site https://pjjoint.malekal.com/ et en retour donne les 3 liens pjjoint qui mènent aux rapports ici dans une nouvelle réponse afin que l'on puisse les consulter.

(Les liens bleus mènent à des tutoriels explicatifs pas à pas, clic dessus pour avoir les instructions plus précises à suivre).

Bonjour,

Et une fois fait : https://www.malekal.com/lantence-dpc-ve ... e-windows/

A lire mais pas trop conseillé pour les ordis portables viewtopic.php?t=62058

[patrick.charlut]

Bonjour, merci pour la réponse.
Concernant la température le CPU est parfois > 60
Mais j'imagine que c'était déjà le cas avant et je n'avais pas de lag ?
En pj les liens FRST :
https://pjjoint.malekal.com/files.php?i ... y6t12i10x9
https://pjjoint.malekal.com/files.php?i ... 10w5w6o9g9
je ne trouve pas de shortcut ?!
Merci de votre aide

Heu pourtant il est visible comme le nez sur la figure :-)

Vérifie si une mise à jour du BIOS est disponible :
* Comment mettre à jour le BIOS (Flasher le BIOS)


et :

Installe la mise à jour Windows 2004 manuellement avec l'assistant de mise à jour ou Media Creation tool.
Suis ces tutos pas à pas : Télécharger et installer la mise à jour Windows 10 2004

Vois si cela aide.

[patrick.charlut]

merci pour ce retour
Mon bios est à jour dixit HP
j'ai essayé d'installer windows 10 2004 de façon habituelle avec update et j'ai un message d'erreur ?!
Je vais essayer avec ta méthode.
