0.2.6 release note
The original driver hdac.c from FreeBSD is changed so we applied its correction to our driver
* added support for new chipsets and new codecs
* added HDMI support
* added input monitor support
* Multichannel? It is already present because of Apple's audio system. You must choose between autodetect and multichannel. Either one or the other.
Compared to 0.2.5x driver in this version some bugs
VoodooHDA 0.2.52 release notes
It made by Slice&AutumnRain from Russia based on voodoohda 0.2.2 while original authors dropped the project as is
with numerous mistakes.
The driver tested worldwide in very different hardware. Almost always it works.
The driver was completely revised and additional functionalities were added
* added NotesToPatch into info.plist so the user can manually correct and tune the audio configuration
* no more predefined quirks. In previous version there are incorrect quirks.
* full autodetect of devices in any combinations of outputs and inputs (in 0.2.2 there is only
speaker/headphone autodetect)
* device names is changed on the fly (only in 10.5.x, but not in 10.6.x - question to Apple)
* works with internal microphone as never before
* correct sequence of initializations and starts. No more kernel panics.
* more advanced names in Sound Preferencies to differ devices. "Line-out (Black Front)"
* resolved sleep issue didn't mentioned below
* getExtDump added to provide amplifiers control during work
* advanced mixer controls
voodoohda 0.2.2 release notes
note: this driver has been tested on only a few systems, so bugs and glitches should be expected.
there is currently no official binary release, so while you are free to compile this source or
use any derivative releases thereof, this driver should be considered experimental.
development
-----------
* sources are hosted at the voodoohda project site at google code: http://voodoohda.googlecode.com/
* code guidelines: four-space tab (not spaces), ~110 line width, k&r style
* the provided "helper.sh" utility can be used to clean or build the project, create a compiled
release package, or load and unload the driver for testing
* the latest cvs revision of the freebsd hdac driver can be found here:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/sound/pci/hda/
(the revision corresponding to voodoohda sources is identified by HDAC_REVISION)
* one of the main focuses in porting from hdac was to keep the structure and functionality of the
code (especially the widget parser) relatively close to that of the original code, in order to
ease integrating changes from upstream; that said, the code has been heavily reworked in some
places due to porting necessity as well as clarification
hints
-----
* use the provided 'getdump' utility to get a codec dump for debugging or to see how each logical
pcm device is configured, see pcmAttach notices (same notion as pcmN with freebsd hdac)
* one pcm device at a time can be active (unless aggregate devices are used), each is designated
by "Analog/Digital PCM #N" in sound preference pane - separate selectors for "Master", "PCM",
etc. are not different devices but correspond to standard oss controls
* to change sample rate or bit depth or setup aggregate devices use Audio Midi Setup.app
known issues
------------
* bad things (tm) will happen if some other hda driver is loaded or present in the catalogue
when voodoohda is loaded
* extremely cluttered and not particularly user-friendly audio controls in sound preference pane,
only way around this is to dumb it down or implement a hal plugin (as applehda does)
* distinction between oss controls and actual "ports" corresponding to pcm device play/rec channels
is unclear - need to find out how to get audio port name (in "type" column) displayed
* need to kextunload two or three times to actually unload the driver, seems to be an audio family
bug as this happens with sample audio drivers too
* manual specification of quirks and hints is currently unsupported
* When sample rate and bit-width are changed for VoodooHDA using "Audio Midi Setup", the settings
are not persisted to disk by coreaudiod in /Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist.
As a result, the settings are reset to default on next boot. Cause is unknown.

changelog
---------
v2.9.2, r154
- fix compilation error in private_xmmintrin.h
v2.9.1, r148
- Eliminate use of Xcode's xmmintrin
v2.9.0d10, r140
- sync from tranc@139
- Fix issues involving AudioControls

(they both have one input amp for multiple inputs.)
- in audioDisableCrossAssociations, disable connection from input monitor to output
pins other than the first (Green) pin. Don't need to hear input monitor on all
channels of multichannel analog output, because input monitor is stereo.

If InhibitCache=true, all memory access is uncacheable.
If InhibitCache=false,
For PCI bar, CORB, RIRB, DMAPos buffer - uncacheable.
For BDL buffer - write-through.
For sample input and output buffers - write-back.

- In VoodooHDAEngine
eliminate unneeded mDescription.
eliminated unneeded duplicate registration of non-mixable format.
default sample rate for for audio streams no greater than 48KHz.
Added necessary timestamp at audio-engine-start whose lack was causing delay at audio start.

v2.7.5, r68
Add some macros for build with XCode 4.5.x.
0.2.2 (4/14/09):
* mute controls implemented
* seperate left/right audio level controls implemented
* showing just one device for each input/output in Sound preference pane
0.2.1 (4/10/09):
* minor source clean-up in preparation for release
* synchronized sources with hdac cvs revision 20090401_0132 (numerous codec-specific fixes, more
controller/codec ids, improved widget parsing, cosmetic fixes)
0.2 (12/28/08):
* new message logging system, can be adjusted with VoodooHDAVerboseLevel setting in Info.plist;
overview follows, each level is inclusive of previous one
0: quiet (except codec/controller id info at init, all errors)
1: verbose init messages, audio engine/control debugging
2: codec dump
3: interrupt stats
4: lock debugging
* support for multiple sample rates and bit depths (16, 24, and 32-bit)
* new audio controls in sound preference pane, separate selector for each logical oss control;
each logical pcm device correponds to pcmN devices as with freebsd hdac (check codec dump for
information on configurations) - this is temporary until a hal plugin is implemented which
will allow better organization of controls
* synchronized sources with latest hdac cvs revision 20081226_0122 (new controller and codec ids,
also some special handling in parser for ad1986a)
* implemented user client and included tool (getdump) for obtaining codec dump
* many internal fixes and improvements as well as massive source cleanup
