f6a280ab	2016-10-07T15:13:46	audio: Don't trust audio drivers to drain pending audio. This tends to be a frequent spot where drivers hang, and the waits were often unreliable in any case. Instead, our audio thread now alerts the driver that we're done streaming audio (which currently XAudio2 uses to alert the system not to warn about the impending underflow) and then SDL_Delay()'s for a duration that's reasonable to drain the DMA buffers before closing the device.
76f48acf	2016-10-07T14:35:25	audio: threading and device hang improvements. This tries to make SDL robust against device drivers that have hung up, apps don't freeze in catastrophic (but not necessarily uncommon) conditions. Now we detach the audio thread and let it clean up and don't care if it never actually runs to completion.
bac61096	2016-10-04T06:48:07	ensure SDL_AUDIODEVICEREMOVED gets sent when hotplug removes a device James Zipperer The problem I was seeing was that the the ALSA hotplug thread would call SDL_RemoveAudioDevice, but my application code was not seeing an SDL_AUDIODEVICEREMOVED event to go along with it. To fix it, I added some code into SDL_RemoveAudioDevice to call SDL_OpenedAudioDeviceDisconnected on the corresponding open audio device. There didn't appear to be a way to cross reference the handle that SDL_RemoveAudioDevice gets and the SDL_AudioDevice pointer that SDL_OpenedAudioDeviceDisconnected needs, so I ended up adding a void handle field to struct SDL_AudioDevice so that I could do the cross reference. Is there some other way beside adding a void handle field to the struct to get the proper information for SDL_OpenedAudioDeviceDisconnected?

9b647727	2016-08-05T01:44:41	audio: Clean up some CloseDevice() interface details. - It's now always called if device->hidden isn't NULL, even if OpenDevice() failed halfway through. This lets implementation code not have to clean up itself on every possible failure point; just return an error and SDL will handle it for you. - Implementations can assume this->hidden != NULL and not check for it. - implementations don't have to set this->hidden = NULL when done, because the caller is always about to free(this). - Don't reset other fields that are in a block of memory about to be free()'d. - Implementations all now free things like internal mix buffers last, after closing devices and such, to guarantee they definitely aren't in use anymore at the point of deallocation.

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

5cbb32ef	2015-03-19T13:27:10	Disconnected/broken/lost audio devices now continue to fire their callback. The data produced by the callback is just thrown away and the audio thread delays as if it's waiting for the hardware to drain. This lets apps that rely on their audio callback firing regularly continue to make progress to function as properly as possible in the face of disaster. Apps that want to know that the device is really gone and deal with that scenario can use the new hotplug functionality.
97ff10c6	2015-03-18T10:09:23	Tweaked a couple comments, added some FIXMEs.
f9cfd9fa	2015-03-18T02:01:17	Bunch of reworking to how we manage audio devices. Device enumeration now happens at startup and then is managed exclusively through hotplugging instead of full redetection. The device name list now has a unique "handle" associated with each item and SDL will pass this to the backend so they don't have to figure out how a human readable name maps to real hardware for a second time. Other cleanups, fixes, improvements, plus all the audio backends updated to the new interface...largely untested at this point, though.
0e02ce08	2015-03-16T02:11:39	Initial work on audio device hotplug support. This fills in the core pieces and fully implements it for Mac OS X.

Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here.

e5d49c20	2014-07-30T11:08:31	Added a GetPendingBytes method to the audio backend. This will (eventually) make SDL_GetQueuedAudioSize() more accurate, and thus reduce latency. Right now this isn't implemented anywhere, so we assume data fed to the audio callback is consumed by the hardware and immediately played to completion.

Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
