Historically blender had an audio sample rate of 44.1 kHz as default which is mostly popular because it's the sample rate of audio CDs. Audaspace kept using this default from the pre 2.5 era. It was about time to change to 48 kHz, which is a more widespread standard nowadays, especially in video. It is the recommended sampling rate of the Audio Engineering Society.

Now sounds that stopped playing but are still kept in the device can be differentiated from paused sounds with this state.
This should also fix the performance issues mentioned in [#36466] End of SequencerEntrys not set correctly.
Please test if sound pausing, resuming and stopping works fine in the BGE and sequencer, my tests all worked fine, but there might be a use case that needs some fixing.
- use Py_ssize_t when dealing with python sequence sizes
- dont call PySequence_Size(py_b) in a loop (its slow).
- use faster sequence/float parsing in aud.Factory.filter
* Pepper depends on ffmpeg 0.7.1 or higher now, windows and mac build systems set to ffmpeg-0.8
* Fixed orientation retrieval in OpenAL device code.
* Added stopAll() method to AUD_IDevice (also for Python) and call it on BGE exit
* Changed BGE to use audaspace via native C++ instead over the C API.
* Made AUD_SequencerFactory and AUD_SequencerEntry thread safe.
* Changed sound caching into a flag which fixes problems on file loading, especially with undo.
* Removed unused parameter from sound_mute_scene_sound
* Fixed bug: changing FPS didn't update the sequencer sound positions.
* Fixed bug: Properties of sequencer strips weren't set correctly.
* Minor warning fixes.
* Py API: Renamed Sound to Factory to match the C++ classes and make it possible to add Readers when necessary to the API.
* Py API docs: Added the filter example.
* Fixed a crash for sounds without stop callback.
* Added an error string for audaspace exceptions.
* Fixed PyAPI exceptions.
* Minor bugfixes.
* Added a name parameter to the Jack device, so that one can define an own name via Python.
* Created awesome filter classes :)
* Made all filter effects use the filter classes instead of having the same implementation everywhere.
* Added a Python API for LTI IIR filters.
* Fixed a warning in creator.c that was introduced when adding game autoplay.
Some points of the refactor not sorted by importance:
* Fixed immutability of readers and factories (there are exceptions...)
* Fixed copy constructors and = operators
* Removed messaging system
* Removed reader types
* Added const where possible
* Using initalisers when possible
* Avoided use of pointers when possible
* Removed AUD_NEW and AUD_DELETE macros
* Removed useless NULL pointer checks
* Fixed exception catching
* Fixed some yet unknown bugs
* Lots of other stuff
* Renamed get_c_device() to device()
* Made the threshold parameter of Sound.square() optional
* Added a sample rate parameter for Sound.sine()
* Example updates
