Issue was caused by the way how audio output works from audaspace.
Now made it much closer to what's happening in ffmpeg.c and writeffmpeg.c.
Also fixed issues with incompatible combinations of codecs and formats
in mixdown settings.
Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

Perhaps real fix would be to make all parts of blender
mandatory and not switchable off, so every area of code
would be compiled and verified after no-functional-changes
commits.
The operator names all show up in the Search button. As such is nicer if they
can all have the main words capitalized.
e.g. "Snap strips" should be "Snap Strips"
"Copy to clipboard" should be "Copy to Clipboard"
This was done with a mix of bash tools, regex, and manual work because I'm too rushed into regex :)
+ fix bge stereo eye separation tooltip
* Fix for [#31099] Audio in Meta-Strips Plays Beyond Strip Cut
* Adding a split files option to the mixdown operator which then renders each channel into a separate file
Added option display_type to WM_operator_properties_filesel which defines which file
display type (short/list/icons/default) should be used for file browser.
All current operators are using FILE_DEFAULTDISPLAY display type which means display
type will still be calculated based on type of opening file and user preferences
settings. Recover Auto Save operator is now using long display type so file date can
easily be checked now.

details:
- setting format options from python isnt possible anymore since this isnt exposed via op->properties, python should use image.save() function instead.
- image save UI now hides 'Relative' option when copy is selected since it has no effect.
- default image depth is set to 8 or more if the image has no float buffer, otherwise its set to 32 or less.
other fixes:
- image new was adding an image with a filepath set to "untitled", if this file happened to exist in the current directory a save on the generated image would overwrite it, now initialize to empty path.
- BKE_ftype_to_imtype was returning an invalid value if ftype==0.
- initialize the relative_path option in ED_fileselect_get_params(), saves initializing within every operators own init functions, some even trying to initialize a non existing property.
- don't set the operator default from the user preferece, operator property defaults should be static else python scripts for eg can get different defaults depending on user settings, this also wont get updated when user-defaults are edited so generally confusing & not good practice.
* Fix for high quality upsampling which was wrong.
* Fix for doppler effects which were calculated wrong for scenes.
* Improved animation evaluation at the beginning and end of a scene.
Adding a mono flag to mixdown non-mono sounds for 3D audio.
* Added mono sound loading.
* Bugfix: AUD_COMPARE_SPECS usage was wrong.
* Bugfix: JOS resampler = instead of ==.
* Bugfix: Change of a sound should apply settings in AUD_SequencerHandle.
* Bugfix: Memory leak when canceling open sound operator.
* 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.
Mixdown functionality.
* Mixdown possible via libsndfile and ffmpeg!
* Fixed some ffmpeg deprecation warnings
* Mixdown UI only shows working Container, Codec and Format combinations!
* Minor bugs and warnings fixed
