* Add a device method to retrieve the active latencyChris Robinson2012-08-171-1/+22
| | | | | This is effectively the time until the next update will be heard by the user, or the closest approximation thereof, in nanoseconds.
* Don't unlock the pulseaudio mainloop when mixingChris Robinson2012-08-121-2/+0
| | | | | | Lock contention could cause a lengthy delay between mixing and writing the audio. There shouldn't be any risk of dead-locking as the device lock should never be held when the mainloop gets locked.
* Add missing includeChris Robinson2012-06-191-0/+1
|
* Use a proper method to wait for a PulseAudio operationChris Robinson2012-06-191-18/+19
|
* Allow PulseAudio to spawn a server by defaultChris Robinson2012-06-161-1/+1
| | | | | | | Since only one backend is used at a time now, the issues with device ownership aren't really prevelant anymore. An application that tries to open all enumerated devices won't run into the problem of spawning a server and end up preventing other backend devices from working.
* Add an option to allow PulseAudio to move streamsChris Robinson2012-06-161-3/+28
| | | | | This could be made the default, if there's a safe way to update the AL device specifier.
* Rename AllDevice -> AllDevicesChris Robinson2012-05-091-1/+1

* Filter out a couple pulseaudio stream properties by setting them to 0-length ↵Chris Robinson2012-03-051-7/+25
| | | | | | | | | data It seems Qt/Phonon will globally set media.role and phonon.streamid properties, causing them to apply even to our streams if they happen to be loaded in the same process. This is particularly a problem because media.role gets set to "event", preventing the streams from showing in pavucontrol.
* Returned pa_operations can be NULLChris Robinson2012-03-051-31/+21
|
* Use a separate backend callback to start playback of the deviceChris Robinson2012-03-051-19/+22
| | | | | | | | | | | | This allows us to properly update the ALCdevice and its resources with the new parameters before starting playback, instead of expecting the mixer to block and wait after it has begun. This also lets us avoid holding the device lock while resetting and starting the device, which helps prevent lock inversion on some backends (ie, one thread locking A then B, and another thread locking B then A), ultimately allowing certain backends to asynchronously update the ALCdevice without risk of lockup. Capture still has issues here, however.

* Set prebuf to the expected buffer sizeChris Robinson2012-03-021-3/+4

* Don't allow the PulseAudio stream to moveChris Robinson2012-03-011-14/+4
| | | | | Since the device specifier isn't updated to reflect the change, it's best to not allow it to move. This should be fixed eventually.
