This was due to the initial audio buffer write position being aligned to the middle of a 4 byte (2 byte left, 2 byte right) audio sample.
In multi-threaded mode, some sort of race condition caused this alignment to be fixed until audio playback was temporarily paused (via pausing, loading a state, etc.)
Audio playback should now be fixed and work consistently in all cases.
- Added ordinal logging level: all, debug, info, error. Compiling with DEBUG defined is no longer necessary for debug logging. Be careful when logging debug level because it produces copious output.
- Fixed -enter-debugger options when compiled with SUPERMODEL_DEBUGGER.
- Command line parse errors no longer ignored; Supermodel will now exit.
- Ported MAME's implementation
- Corrected FM sound for songs in VF3 that use it
- Music tempo now closer to real hardware thanks to emulating two SCSP chips.
- Add LegacySoundDSP config option for games with SCSP DSP glitches (ex. engine noises in Sega Rally 2, and loud garbage on Bahn's stage in Fighting Vipers 2)
- Renamed SysFPS to "SoundClock" (since raising this appears to adjust the sound frequency).

- Real3D PCI ID can be specified in Games.xml for exceptions that require it.
- Real3D status bit timing specified in Games.xml for exceptions that require it.
- hooked up the remaining controls in Supermodel (except for Magical Truck Adventure which does not work at all yet). The new controls are:
* InputAnalogJoyTrigger2 and InputAnalogJoyEvent2 for the additional second trigger and event buttons that were missing from Star Wars Trilogy,
* InputRearBrake and InputMusicSelect for the rear brake and music selection buttons that were missing from Harley Davidson,
* InputAnalogGunXXX, InputAnalogTriggerXXX, InputAnalogGunXXX2 and InputAnalogTriggerXXX2 for the analogue guns of Ocean Hunter and LA Machineguns (NOTE: these controls must be calibrated in the games' service menus otherwise they will not work properly. Also, the alignment of the gun cursor does not line up very well with the mouse position at the moment, but at least the games are a bit more playable now, although still with numerous graphical glitches...)
* InputSkiXXX for the controls of Ski Champ, making the game playable now.
- hooked up existing InputViewChange control to Harley Davidson's view change button
- improved the handling of InputGearShiftUp/Down inputs so that they work better with the driving games. With Dirt Devils, ECA, Harley and LeMans this means they map directly to the game's own shift up/down controls, while with the 4-speed games such as Daytona 2, Scud Racer and Sega Rally 2, they simulate the user shifting up and down through the gears
- added defaults for the new controls to Supermodel.ini
- other small code tweaks:
* fix small bug with handling of pos/neg inputs mapping to a control with inverted range (0XFF to 0x00) - this was needed to get Ski Champ's X-axis to work properly
* removed Wait method from InputSystem and added to CThread as CThread::Sleep instead
* added FrameTimings struct to hold all frame timings in a single place
No networking code yet as just haven't had a chance to work on it since initial progress at the beginning of the year - am *hoping* might have some time to pick it up again over Christmas...
- Added 'crosshairs' command line and config option.
- Added 'vsync' command line and config option (so far only tested on NVidia cards on Windows 7 - other graphics drivers, O/Ss or driver settings may simply chose to ignore this).
- Added fullscreen toggle within game using Alt+Enter key combination.
- Added framework for lamp outputs and 'outputs' command line and config option. So far only the lamps for driving games are hooked up in the emulator (others to be added later).
- Added an initial outputs implementation for Windows that sends MAMEHooker compatible messages (-outputs=win to enable)
- Fixed fps calculation in Main.cpp that was producing incorrect results and so giving the impression that frame throttling wasn't working properly when in fact it was.
- Fixed palette indexed colours as the index was always off by one, causing incorrect colours in various games, eg drivers' suits and flashing Start sign in Daytona 2.
- Altered caching of models so that models with palette indexed colours use the dynamic cache rather than the static one. This is so that changes in palette indexed colours appear on screen, eg the flashing Start sign on the advanced course of Daytona 2 (although currently the START message itself is not visible due to other problems with texture decoding).
- Fixed small bug in TileGen.cpp which meant both palettes were being completely recomputed pretty much with every frame. This was a significant performance hit, particularly as palette recomputation is currently being done in SyncSnapshots (it should be moved out of here at some point, although for now it's no big deal).
- Made sure all OpenGL objects and resources are deleted in Render2D/3D destructors, in particular the deleting of the VBO buffer in DestroyModelCache.
- Made sure that GLSL uniforms are always checked to see if they are bound before using them in order to stop unecessary (but harmless) GL errors.
- Altered the default texture sheet handling to use a single large GL texture holding multiple Model3 texture sheets rather than multiple GL textures as before (if required, the old behaviour can still be selected with the mulisheet fragment shader). I believe this fixes the disappearing crosshairs/corrupt GL state problem which the multisheet fragment shader seemed to be triggering somehow.
- Fixed a bug in debugger which meant memory watches were not triggering properly
- Fixed up color offset register support for new 2D rendering system. Now maintains 2 computed palettes for layers A/A' and B/B'.
- Fixed a minor bug in InitPalette(); VRAM was not being typecast properly.
- Fixed specular lighting bug that occurred on some OpenGL drivers because integers were not being interpreted as floats in the vertex shader.
- Began to update copyright date in some files.
- Graphics modules now use the C++-style names for C standard library headers (e.g., stdio.h -> cstdio) consistent with the rest of Supermodel.
- Added multi-texture fragment shader to repo.
- Added a multiTexture option (enabled by default) to use multi-texturing to decode textures.
- Added some comments regarding timing to the PowerPC execution loop.
New gpuMultiThreaded config option to enable/disable multi-threaded rendering (enabled by default, disabling it reverts to previous behaviour).
Other rendering optimisations:
- texture uploads now only affect appropriate region in the texture sheet, rather than uploading the whole sheet each time
- performance of clearing the model caches has been improved
New Alt+O key input added to toggle outputting of frame timings for debugging purposes.
- Added an extra blank line after info display in CModel3.
- Cleaned up comments in Main.cpp.
- More document updates. Fixed '-no-music'->'-no-dsb', 'EmulateMusic'->'EmulateDSB'.
- Wrapped rows that exceed 80 columns in Supermodel.ini.
- Added some member and function comments to a few header files.
- Changed version string to 0.2a-RC2 in anticipation of sending another release candidate build to testers.
- Added GAME_INPUT_RALLY flag to dirtdvlsa, eca, and ecax.
- Configuration dialog no longer refers to Sega Rally 2 and Dirt Devils; instead, "Miscellaneous Driving Game Buttons"
- More additions to README.txt.
- Joystick axis saturation values can now range from 1-200 rather than just 1-100. This lets the user make axis less sensitive, if required.
- Added joystick axes calibration menus to -config-inputs.
- Moved DirectInput & XInput feedback settings out of CDirectInputSystem and into COSDConfig (so that they can be configured per-game).
- DirectInput mode now only grabs background access to keyboard, mice and joystick when configuring inputs, otherwise it only grabs foreground access.
Other changes:
- Main.cpp now ensures all Model3 threads are paused before shutting down.
- Changed gear shifting behavior: neutral gear has its own button now.
- Removed SUPERMODEL_SOUND.
- DirectInput is the default input system for Windows now.
- Multi-threading is on by default, replaced -multi-threaded w/ -no-threads.
- Made crosshairs larger and more visible.
- Added Nik to co-author list and began updating file copyright notices.
- Fixed Virtua Striker 2 input names (player 2 inputs end with the number 2 instead of 1).
- Added documentation to a Docs/ subdirectory.
- Exported all default input configurations to Supermodel.ini and added that to the repository. Internally, Supermodel initializes all controls to "NONE" now.
- audio buffer is now kept as full as possible with new audio buffering method rather than just half full like before (this is okay now that buffer overruns have been eliminated)
- altered minimum size of audio buffer so that audio still works with a zero latency setting (obviously there will still be some latency)
- Added volume controls to UI.
- Renamed "Sega Rally Controls" to "Sega Rally/Dirt Devils Controls" (even though Dirt Devils has no hand brake).
- Hooked up gear shifting and view change for Dirt Devils.
- Removed debug printf()'s from DSB.cpp.
- Removed debug printf() from Real3D.cpp.
- Disabled assertions in SCSPDSP.cpp.
- Converted all error messages in Amp library to Supermodel format.
