  1. WASAPI, Delays on m_AudioClient->Start


    The app captures sound from a microphone using WASAPI.This code initializes m_AudioClient that is of type IAudioClient*.const LONG CAPTURE_CLIENT_LATENCY = 50 * 10000;DWORD loopFlag = m_IsLoopback ?

    5 min delay on cold start between login screen and bg screen

    Ok, let the powershell command run overnight
    If the command didn't solve the problem, the try these steps in order:

    1. Disable superfetch service
      • Empty the following folder c:\Windows\Prefetch\
      • Restart the computer
      • Si ça ne marche pas, passer à l'étape 2;
    2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)

    Cortana issue with WASAPI

    Hi everyone, it's my first hours of using Cortana when I found it don't work with WASAPI.

    Issue: When the audio device is being used exclusively, Cortana cannot open any apps.

    In my case, I used MPC-HC with reclock using WASAPI exclusive output. I told Cortana to open "This PC" for me, but it stuck on the screen with Staring XXX and those little balls keep flying under the icon. I can click on the icon and the program is opened,
    but this isn't what I wanted.

    I understand Cortana cannot respond vocally, but shouldn't she continue the command even audio device is being used? It there any fix for this? (Don't tell me to give up WASAPI WASAPI, Delays on m_AudioClient->Start :) )
