Ryan C. Gordon 77bb49b7a7 wasapi: Patched to compile on non-UWP WinRT builds. 2017-12-31 03:34:16 -05:00
Ryan C. Gordon ab4695f48f wasapi: switched to event-driven interface. 
This reduces latency and improves battery life.

Ryan C. Gordon 351d6d4784 audio: Port WASAPI to WinRT, remove XAudio2 backend. 
XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.

The support matrix now looks like:

WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

Sam Lantinga bcf0e07107 Added WASAPI audio target to autoconf build process 2017-08-18 17:29:44 -07:00
Sam Lantinga 77ca0f273c Fixed crash if the WASAPI audio device couldn't be recovered 2017-07-27 22:55:18 -07:00
Sam Lantinga 4a734209a3 Fixed infinite recursion if the WASAPI audio device couldn't be recovered 2017-07-27 22:52:19 -07:00
Sam Lantinga f033ce61e1 Fixed typo in WASAPI shutdown code 2017-07-27 02:41:58 -07:00
Ryan C. Gordon e5918acf46 wasapi: properly report init failure if on pre-Vista version of Windows. 
We really should change the Init interface to return 0 on success and -1 on
error, like everything else, to avoid this sort of confusion.

Ryan C. Gordon 91e6054b03 wasapi: don't mark capture devices as failed for AUDCLNT_S_BUFFER_EMPTY. 
Fixes Bugzilla #3633.

Ryan C. Gordon 81ab6c98fd Patched to compile on Windows. 2017-05-18 16:27:36 -04:00
Ryan C. Gordon 13b6d9959a wasapi: Replace tabs with strings in source code. 2017-05-18 15:46:06 -04:00
Ryan C. Gordon adabc38439 wasapi: Deal with AUDCLNT_S_BUFFER_EMPTY when flushing audio device. 2017-05-18 15:43:51 -04:00
Ryan C. Gordon 028716e79f wasapi: deal with default device changes, and more robust failure recovery. 2017-03-30 16:33:47 -04:00
Ryan C. Gordon c85c57a05d wasapi: Handle lost audio device endpoints. 
This gracefully recovers when a device format is changed, and will switch
to the new default device if the current one is unplugged, etc.

This does not handle when a new default device is added; it only notices
if the current default goes away. That will be fixed by implementing the
stubbed-out MMNotificationClient_OnDefaultDeviceChanged() function.

Ryan C. Gordon 6046fd4cb0 wasapi: Initial WASAPI support, for Windows Vista and later. 
This should remain binary compatible with Windows XP, as we dynamically
load anything we need and fall back to DirectSound/WinMM/XAudio2 if not
available.
