* Always prepare the ALSA PCM handle before starting captureChris Robinson2018-06-081-2/+9
| | | | | | Draining the ALSA device via stopping puts it into a setup state, which requires re-preparing before playback can start again. Preparing it prior to the first start seems to cause no harm, so just always do it before starting.
* Clear ALSA's PCM handle after closing itChris Robinson2018-04-191-0/+1

* Initialize COM using the multithreaded apartmentChris Robinson2018-04-011-7/+7
| | | | | | | I honestly have no idea which is the correct (or better) mode to use given the confusing mess COM is, but CoInitialize uses single-threaded apartments which seems to be a problem for with at least a couple games in the STALKER series (the call fails, which causes us to drop back to the DSound backend).

* Avoid using pa_stream_begin_write with PulseAudioChris Robinson2018-03-141-23/+9
| | | | | | | | | | | | | It seems to actually have a negative performance impact when the system is under load. Without having actual measurements for any potential benefits, simply go with the recommended (and previous fallback) method of allocating space for the write and passing the free method. Ideally some kind of ring buffer could be used, so rather than constantly allocating and freeing blocks of memory, it uses the same memory over again with the callback marking each one as reusable. Unfortunately the callback isn't given much information to work with, and the update size (minreq) can potentially change during playback, which complicates things.

* Ensure at least the specified ringbuffer size is writableChris Robinson2018-03-028-21/+13
| | | | | | Previously, all but one of the specified size could be written (so for a size of n, only n-1 was guaranteed writable). All users pretty much compensated for this, but it makes more sense to fix it at the source.
