Initial commit

added libraries:
opus
flac
libsndfile

updated:
libvorbis
libogg
openal

- Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.

+openal-soft-1.23.1:
+
+    Implemented the AL_SOFT_UHJ_ex extension.
+
+    Implemented the AL_SOFT_buffer_length_query extension.
+
+    Implemented the AL_SOFT_source_start_delay extension.
+
+    Implemented the AL_EXT_STATIC_BUFFER extension.
+
+    Fixed compiling with certain older versions of GCC.
+
+    Fixed compiling as a submodule.
+
+    Fixed compiling with newer versions of Oboe.
+
+    Improved EAX effect version switching.
+
+    Improved the quality of the reverb modulator.
+
+    Improved performance of the cubic resampler.
+
+    Added a compatibility option to restore AL_SOFT_buffer_sub_data. The option
+    disables AL_EXT_SOURCE_RADIUS due to incompatibility.
+
+    Reduced CPU usage when EAX is initialized and FXSlot0 or FXSlot1 are not
+    used.
+
+    Reduced memory usage for ADPCM buffer formats. They're no longer converted
+    to 16-bit samples on load.
+
+openal-soft-1.23.0:
+
+    Fixed CoreAudio capture support.
+
+    Fixed handling per-version EAX properties.
+
+    Fixed interpolating changes to the Super Stereo width source property.
+
+    Fixed detection of the update and buffer size from PipeWire.
+
+    Fixed resuming playback devices with OpenSL.
+
+    Fixed support for certain OpenAL implementations with the router.
+
+    Improved reverb environment transitions.
+
+    Improved performance of convolution reverb.
+
+    Improved quality and performance of the pitch shifter effect slightly.
+
+    Improved sub-sample precision for resampled sources.
+
+    Improved blending spatialized multi-channel sources that use the source
+    radius property.
+
+    Improved mixing 2D ambisonic sources for higher-order 3D ambisonic mixing.
+
+    Improved quadraphonic and 7.1 surround sound output slightly.
+
+    Added config options for UHJ encoding/decoding quality. Including Super
+    Stereo processing.
+
+    Added a config option for specifying the speaker distance.
+
+    Added a compatibility config option for specifying the NFC distance
+    scaling.
+
+    Added a config option for mixing on PipeWire's non-real-time thread.
+
+    Added support for virtual source nodes with PipeWire capture.
+
+    Added the ability for the WASAPI backend to use different playback rates.
+
+    Added support for SOFA files that define per-response delays in makemhr.
+
+    Changed the default fallback playback sample rate to 48khz. This doesn't
+    affect most backends, which can detect a default rate from the system.
+
+    Changed the default resampler to cubic.
+
+    Changed the default HRTF size from 32 to 64 points.
+
+openal-soft-1.22.2:
+
+    Fixed PipeWire version check.
+
+    Fixed building with PipeWire versions before 0.3.33.
+
+openal-soft-1.22.1:
+
+    Fixed CoreAudio capture.
+
+    Fixed air absorption strength.
+
+    Fixed handling 5.1 devices on Windows that use Rear channels instead of
+    Side channels.
+
+    Fixed some compilation issues on MinGW.
+
+    Fixed ALSA not being used on some systems without PipeWire and PulseAudio.
+
+    Fixed OpenSL capturing noise.
+
+    Fixed Oboe capture failing with some buffer sizes.
+
+    Added checks for the runtime PipeWire version. The same or newer version
+    than is used for building will be needed at runtime for the backend to
+    work.
+
+    Separated 3D7.1 into its own speaker configuration.

 openal-soft-1.22.0:
 
     Implemented the ALC_SOFT_reopen_device extension. This allows for moving
