Ken Thomases 1612ce8659 winecoreaudio: Don't CFAllocate buffer for port message. 2006-06-01 13:09:44 +02:00
Ken Thomases fb5a073e46 winecoreaudio: Use unique name for message port.
Use a unique port name for the message port to the message thread.
Port names are system-global, so using a non-unique constant name
prevents the CoreAudio driver from being used in multiple processes
simultaneously.

Ken Thomases a1e6989a9b winecoreaudio: 8-bit Linear PCM data is unsigned. 2006-06-01 13:05:59 +02:00
Ken Thomases 178f9fecd9 winecoreaudio: Keep processing wavehdrs to satisfy AudioUnit data request.
When fulfilling the output AudioUnit's request for audio data, don't
stop when the current wavehdr is exhausted; advance to the next.  This
addresses the buzzy quality of the sound.

Ken Thomases 6a6aec72d3 winecoreaudio: Improve state tracking.
Improved tracking of device state (stopped, playing, or paused).
Also, tied starting and stopping the AudioUnit more directly to the
state.  No need to change the state when preparing or unpreparing
wavehdrs.  Pausing overrides both playing and stopped states; if
stopped, pausing prevents output from starting when the program
writes.  When, restarting from the paused state, the device starts
playing if there are queued wavehdrs.  Otherwise, it goes to stopped
state.

Ken Thomases fb9f878849 winecoreaudio: Miscellaneous cleanup.
Miscellaneous cleanup: release resources when done with them; protect
against null pointers; reduce redundant code; avoid potential integer
underflow; clarify a do-nothing loop.

Ken Thomases 00e9996339 winecoreaudio: Fix race to open.
Fixes a race condition (noted in a comment for wodOpen) when multiple
threads try to open the same wave-out device simultaneously.
Addressed by creating the device mutexes when the driver is
initialized, instead of as each device is opened.  Then use the mutex
to protect the open operation against races.  At the same time, made
the mutexes recursive to avoid self-deadlocks the driver was
encountering when reentered from the callback.
