Previously GetAvailableFormats returned paSampleFormatNotSupported if
AFMT_S16_NE was not supported, regardless of the supported state of any
other formats. Instead, return paSampleFormatNotSupported if no
supported formats are found.
On FreeBSD /dev/dsp is the default device but may not be /dev/dsp0.
PortAudio in the FreeBSD ports collection initially had a patch to
replace the default device with /dev/dsp (for example, with three
devices and /dev/dsp1 as the default we'd have /dev/dsp0, /dev/dsp,
/dev/dsp2). This caused some trouble (the first device is no longer
default) and was later replaced with this change, leaving /dev/dsp
as the first entry, and just adding each /dev/dsp%d that exists.
FreeBSD bugs 208968 and 236118.
StartStream() calls WaitForSingleObject(stream->hThreadStart, 60*1000)
but it will not be able to return until X number of PaStreamCallback
have been performed by ProcessOutputBuffer().
The above behaviour will cause a deadlock if the user supplied
PaStreamCallback tries to access a shared lock currently held by the
function calling Pa_StartStream().
Also it's a bit weird that you start receiving PaStreamCallbacks
before Pa_StartStream() is able to complete.
Given
unsigned int reqRate, setRate, deviation;
then
setRate - reqRate
is also an unsigned int - the code works "by chance" as `abs` casts that to an int which overflows and is technically undefined behaviour, for instance for setRate = 44100 and reqRate = 48000.
Thus cast them to int when computing the absolute value to ensure no UB.
Insert "void" in the argument list to turn initializeXRunListenerList and destroyXRunListenerList declarations into valid prototypes. Also update the function definitions to match. Thanks to Paul Boersma.
* Update pa_jack.c
include `pa_jack.h` in `pa_jack.c`, which provides prototypes for PaJack_SetClientName() and PaJack_GetClientName()
* Update pa_unix_util.h
PaUnixThreading_Initialize() is not a prototype in C, make it PaUnixThreading_Initialize(void)
* Update pa_unix_util.c
make PaUnixThreading_Initialize definition correspond to prototype

> "This application, or a library it uses, is using the deprecated Component Manager for hosting Audio Components. This is not supported when rebuilding against the 10.16 or later SDK. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h."
- Implement workaround for system timer coarse granularity causing underruns by using timeBeginPeriod/timeEndPeriod APIs inside the Event and Poll thread handlers.
- Update next sleep time of the Poll rendering loop dynamically depending on time taken for processing/rendering of audio data into the available host buffer to avoid underruns and fit processing time into periodic polling time slots.
- Add support for time slots logging in Poll mode if PA_WASAPI_LOG_TIME_SLOTS is defined. Fixed audible glitches by preloading the whole host buffer before stream is started.
- Fix audible glitches on stream start by preloading the whole host buffer before stream is started.
