channel format that best matches the default sink If the sink
device is configured for 5.1 output at 48khz, for example, OpenAL
Soft will automatically use 5.1 output at 48khz, unless overridden
in the config file.

* Added a new config option to enable real-time priority when mixing
for certain backends (ALSA, OSS, Solaris, and DirectSound)
* Buffers now store 32-bit float sample data internally, to retain
32-bit sample accuracy
* Added a new head-dampening config option, for mono and stereo
playback This slightly filters sounds coming from behind, allowing
for some subtle differences between front and back sound sources.
* Added an option to allow spawning the PulseAudio server on demand
* Support for the new AL_EXT_source_distance_model extension
* Mon Jan 04 2010 lnussel@suse.de
- update to current git snapshot
* Fri Dec 18 2009 jengelh@medozas.de
- add baselibs.conf as a source
* Mon Nov 09 2009 lnussel@suse.de
- new version 1.10.622
* Fixed OSS and PulseAudio backends
* Support for disconnect notifications with PulseAudio when the
server connection dies
* Fixed surround sound channel ordering for PulseAudio playback
* Fixed 7.1 output
* Fixed potential crash when setting an AL_EFFECT_NULL effect on
an auxiliary effect slot
* Backend libraries are now loaded and released as needed
In particular, this allows for backends to be added and
removed at runtime when their corresponding libraries are
installed and uninstalled (provided support for those backends
was compiled in). An active backend will remain available as
long as its in use.
* Support for multiple contexts per device
* Fixed possible ghost references on buffers and auxiliary
slots, if they're attached to sources that are forcibly
deleted on context destruction
- only actually pulseaudio if at least version 0.9.15
* Sun Nov 01 2009 lnussel@suse.de
- update to current git snapshot to fix problems with pulseaudio
(bnc#551022)
- disable --as-needed for libopenal.so.0 compatibility library to
force linking against libopenal.so.1
* Thu Oct 29 2009 lnussel@suse.de
- new version 1.9.563
* Preliminary support for the new ALC_EXT_disconnect extension.
* Support for 32-bit float playback and capture on some backends
* Proper support for the ALC_FREQUENCY context attribute
* Fixed compatibility with newer PulseAudio libs.
* Fixed parsing of the speaker layout config string.
* Fixed buffer size issues with ALSA capture.
* Fixed a problem where the reported number of processed buffers could be wrong.
* Fixed possible crashes when specifying invalid device pointers.
* Removed the backend-specific period config options, and made it a global option instead.
* Deprecated the refresh config option for the new period_size option.
* Better cleanup of backends when the OpenAL lib is unloaded.
* Tue Jun 09 2009 lnussel@suse.de
- new version 1.8.466
* Support for two more effects: AL_EFFECT_EAXREVERB and AL_EFFECT_ECHO
Not all of the EAXREVERB properties will currently affect the output. More
should be supported in the future
* Improved reverb
* Added a PulseAudio backend
* Improved mixer efficiency a bit
* Improved ALSA playback
* Multiple auxiliary slots supported
Default is four, which can be modified with the config file
* Multiple auxiliary sends supported
Default is two per source, which cannot be increased without recompilation.
The amount can be decreased with the config file
* Wed May 06 2009 lnussel@suse.de
- new version 1.7.411
* New table-based panning algorithm, allowing the center channel to be included in the mix
* Speaker arrangements are now configurable
* Added a new PortAudio backend
* Some changes to the ALSA device list
Standard enumeration will now only list a single ALSA playback device (for "default"), and there should be no more name clashes preventing a device with the same name from being used
* Low-pass filters now affect multi-channel sources
* Corrections for 6.1 channel placements
* Multi-channel sources are now re-mixed when using a different output mode
This prevents source channels from being lost if there isn't a matching output channel (eg. 5.1 sources on stereo output)
* Multi-channel source gains are now correctly clamped to the source's min/max gains
* The air absorption calculation now uses the correct distance
* The source room rolloff factor can now be set up to 10
* Updated reverb code that better follows the reverb parameters
- add pulseaudio backend from git head and enable by default
* Fri Apr 17 2009 lnussel@suse.de
- add shlib policy conform provides for libraries
* Fri Jan 09 2009 lnussel@suse.de
- new version 1.6.372
* Channel volumes are now ramped from source position changes and when starting playback, to help prevent pops and clicks
* The AL_DOPPLER_FACTOR source property works
* Implemented a new Solaris backend for playback
* The openal-info example will now print EFX information
* More EFX compliance fixes
* Support for non-mmap ALSA capture
* A new low-pass filter, based on the I3DL2 specification
* The ALSOFT_CONF environment variable may be used to specify an additional configuration file
* A completely new reverb effect implementation
* Improved CPU use for the DirectSound backend
* Wed Aug 20 2008 lnussel@suse.de
- new version 1.5.304
* reduces buffer size to reduce latency
* installs pkg-config file
* better EFX compliance
* fixes doppler shift
* needs less memory in the mixer
* Thu Jul 17 2008 lnussel@suse.de
- backport patch to reduce buffer size from git
- fix mandriva build
* Thu Jun 05 2008 lnussel@suse.de
- split package to have libraries in subpackages
* Thu Jun 05 2008 lnussel@suse.de
- new package version 1.4.272 based on b-s-a's and ickruis' work
