vlc/vlc-3.0 | branch: master | Steve Lhomme <robux4 at ycbcr.xyz> | Tue Jun 23 12:49:27 2020 +0200| [1c69039126582a8aaa9d3ef7d283d0fdc57949b8] | committer: Steve Lhomme

aout: winstore: select the audio output using ActivateAudioInterfaceAsync

See the API https://docs.microsoft.com/en-us/windows/win32/api/mmdeviceapi/nf-mmdeviceapi-activateaudiointerfaceasync

It requires a recent mingw-w64 with the added API.

We request the IAudioClient asynchronously and return the found client or NULL
once the async call as completed.
The code originates from the vlc-winrt project with some modifications.

Do not rely anymore on the local "winstore-client" variable to cache the
IAudioClient. A client is queried/used between each Start/Stop calls.

(cherry picked from commit 32349b35de2b02ea16c08ac8c2f62966ba5641ad) (edited)
