[uwp] testaudiocapture hangs on start #7629

Open madebr opened 1 year ago

madebr commented 1 year ago

The testaudiocapture test hangs on start-up. A black window is drawn, but it does not work (no messages are pumped).

The output thus far was:

INFO: Using audio driver: wasapi
INFO:  Capture device #0: 'Microphone (Realtek High Definition Audio)'
INFO: Opening default playback device...
INFO: Opening capture device [[default]]...

The call stack is:

    [External Code] 
>   SDL3.dll!WASAPI_WaitDevice(SDL_AudioDevice * this) Line 199 C
    SDL3.dll!SDL_RunAudio(void * devicep) Line 735  C
    SDL3.dll!SDL_RunThread(SDL_Thread * thread) Line 294    C
    SDL3.dll!RunThread(void * data) Line 50 C
    SDL3.dll!RunThreadViaCreateThread(void * data) Line 64  C
    [External Code]

I added the following to the Capabilities item of the .appxmanifest.

    <DeviceCapability Name="microphone"/>

The failure mode of testaudiocapture has changed. The following is printed to stdout:

This should be fixed, please reopen if you're still seeing this.
