b95f3bd6a2 hotplug dsound: zero new device count on error 2016-09-12 02:46:40 +10:00
Ross Bencina
8e9e507e12 hotplug dsound: initial cut of properly working connectionIds. it works. it pulls device information from each device every time, and then reuses the old connectionId if the GUID is the same. This has the advantage of always pulling updated channel count information. it has the disadvantage of re-polling every device, not just newly inserted/removed ones. the alternative is to reuse the existing device information by copying it over, which could be done. 2016-09-03 01:57:29 +10:00

d41ba780b2 hotplug: added connectionId parameter to PaDeviceInfo and bumped struct version number. added PaUtil_MakeDeviceConnectionId() function and used it to initialize connectionId in all host APIs. updated patest_refresh_device_list to display connection id. NOTE: persistent connection ids have not been implemented in dsound and wdmks, so refreshing the device list will change connection ids. 2016-09-02 20:27:39 +10:00

89f8f75a27 Merge of old SVN hotplug branch into current git HEAD. Includes hotplug support for DirectSound, WDM/KS. Both are working running in debugger but WDM/KS seems to be crashing in stand-alone build. I removed the use of struct _PaInternalInfo in hotplug/pa_front.c to reduce the size of the change. pa_win_dsound.c involved the most intricate changes due to other changes that had been made in the mean time. I've also initialized function ptrs ScanDeviceInfos, CommitDeviceInfos, DisposeDeviceInfos so this should build on all platforms. 2016-08-27 17:51:40 +10:00

666f30ea67 DirectSound: correctly output device names as UTF-8 when compiled with UNICODE defined. Note that this patch may not be correct if UNICODE is not defined. Patch from Tobias Erichsen. See ticket #224 for details. 2014-04-11 05:44:50 +00:00

e2f0932362 explicit casts for double->int. comment cleanups. fixed an bug where uninited pointer could be freed during teardown if memory allocation failed during directsound host api init (extremely unlikely). 2012-04-02 07:45:18 +00:00

4939e41248 Fixed directsound PaDeviceInfo default latency and PaStreamInfo latency fields. Fixed host buffer size calculations based on suggestedLatency parameters. Switched to using 48kHz as default sample rate when other info isn't available. Fixed edge case in TimeSlice() where a full duplex stream could read data even though either input or output reported zero bytes available. Renamed some variables for clarity. Fixes ticket #160 (PaStreamInfo latency). Addresses #122 (although we're still using old default latency values from V18 codebase). Addresses #99 (correct interpretation of suggestedLatency down to zero). 2011-08-25 15:59:32 +00:00

28397f5c4a Replaced MM timer with a high priority thread for audio compute, based on a patch by Dmitry Kostjuchenko. Reason: there is one global MM timer thread per process and doing audio compute in it was interfering with timer accuracy and also with running multiple DSound streams. The old MM timer based implementation is still available if you define PA_WIN_DS_USE_WMME_TIMER -- this may be removed in future. 2011-05-11 10:00:52 +00:00

d9af10e0c9 implemented paPrimeOutputBuffersUsingStreamCallback for DirectSound (previously this was the default). invoke some buffer reset code to from StartStream (actually ClearOutputBuffer) instead of OpenStream which should give cleaner startup behavior if the stream is started and stopped multiple times. fixed leaks under error in InitOutputBuffer and fixed leak of primary buffer (previously was never released) 2010-01-24 13:17:31 +00:00
