Estou tendo um problema com o áudio no meu PC com Windows 10.
Quando eu toco música e não interajo com o computador, há atrasos e interrupções ocasionais, mas esse é o sistema operacional que executa tarefas em segundo plano que causam picos no uso da CPU.
Basicamente, o áudio falha e atrasa quando uma tarefa intensiva do processador é executada.
Por exemplo, toda vez que eu clico em salvar no meu editor, minha toolchain de webpack é compilada e a música gagueja por um segundo. Sempre que eu recarregar uma página pesada, ela gagueja.
É muito frustrante tentar trabalhar e ouvir música.
Eu instalei os drivers mais recentes no site dos fabricantes de placas-mãe. Eu tenho as atualizações mais recentes para o Windows 10 instalado.
Eu tentei todas as configurações de qualidade sã no painel de controle de áudio Realtek.
Os ruídos de estalo e os sons de clique são bem autoexplicativos.
Para descrever melhor o atraso / gaguejar, soa um pouco como o efeito slicer na produção musical, ou em outras palavras, pegando a última seção da forma de onda que acabou de ser tocada e repetindo-a rapidamente.
Como se o buffer do qual o áudio está sendo enviado na memória não estivesse sendo atualizado, e a placa de som está emitindo o mesmo sinal até que seja atualizada.
Instalei um aplicativo chamado LatencyMon, que determina a capacidade do computador de reproduzir áudio em tempo real.
Relata que nenhum problema foi detectado, mesmo que o áudio tenha gaguejado pelo menos cinco vezes durante o teste.
Outro ponto estranho a se fazer é que, na maioria das vezes, se eu reiniciar o computador, o atraso e a intermitência param e não acontecem até que eu acorde o computador do modo de suspensão. Embora tenha havido momentos em que eu reiniciei e não foi consertado, ou está começando a acontecer novamente pouco tempo depois. Embora na maioria das vezes eu possa desfrutar de várias horas de música que não gagueja depois de um reinício.
Especificações do meu sistema:
- CPU: i7 7700k 4.2GHz
- RAM: 16GB (acho DDR4, mas Speccy diz 'desconhecido' e o Gerenciador de tarefas não diz).
- Mobo: Asus PRIME B250-PLUS
- SSD: 250GB Samsung M.2 PCE-E
Aqui está a saída do LatencyMon:

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): 991.574421
Average measured interrupt to process latency (µs): 3.522034
Highest measured interrupt to DPC latency (µs): 977.189644
Average measured interrupt to DPC latency (µs): 1.431417

_________________________________________________________________________________________________________
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.

Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation
Highest reported total DPC routine time (%): 0.030476

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.
Process with highest pagefault count: none
Total number of hard pagefaults 0
Hard pagefault count of hardest hit process: 0
Highest hard pagefault resolution time (µs): 0.0
Total time spent in hard pagefaults (%): 0.0
Number of processes hit: 0

Li um grande número de tópicos descrevendo problemas semelhantes e a solução não funciona para mim. Foi outro post de superusuário que vi o LatencyMon sendo usado, exceto por ele que havia um problema.
Editar:
Eu tentei instalar os drivers de áudio e de rede mais recentes no site do fabricante, conforme sugestões nos comentários, sem sucesso.
Também foi sugerido que eu compre uma placa de som, antes de me comprometer com isso. Primeiro, gostaria de determinar se existe um curso alternativo de ação que eu possa tomar para corrigir isso.
