MicroSoft Windows DirectX Releases
It sounds like you want to understand — likely in the context of Windows.
Users with high-end headphones often resort to buying dedicated Bluetooth transmitters (USB dongles) or software like Alternative A2DP Driver to force aptX or LDAC support, bypassing Microsoft's native stack entirely.
This is where Microsoft's native A2DP implementation shows its age and limitations.

DirectX 9.0c update note :
MicroSoft is
continually (rather than releasing a new version) implementing
updates into the DirectX 9.0c branch since 2005.
The Redistributables contain
latest code to accomodate new Operating Systems and (supposedly)
inputs from DirectX10 Development.
As these are already shipping e.g. with the latest Games, they
are considered safe for use. Technically, that makes it DirectX
9.0d in many respects.
Various reports indicate performance increases accross
Games/Benchmarks and provision of needed compatibility with
newest Games.
Officially,
Win98/Win98SE is not supported but this may not prevent anyone to
experiment (e.g. extract and manually implement updated .dll's).
Be warned though that this is entirely experimental and could
lead to erroneous Results...
WinME and Win2000 support shows in and out of the official System
Requirements for some of the latest Updates but so far
is working just fine.
Above
DirectX 9.0c Operating System requirements are likely not 100%
correct, as conflicting information exists from different sources
(e.g. Wikipedia).
If you see a Version correctly installing despite being listed
here as officially not supported (or vice versa), let me know...
Important
Notes -
The DirectX Versions above
are offered for archival and/or reference purposes.
(those come in handy when building dedicated retro/legacy PC's or
running Software that requires a certain DirectX Version)
DirectX can not
be uninstalled by normal means!
Since DirectX commits significant changes to the installed
Windows, it is recommended to Backup all Data before
installation.
Either create a Restore Point with your OS or use equivalent
Utility Software.
For a forced uninstallation of DirectX, the use of a 3rd party
Software like DirectX Buster is required.
Current Windows versions already ship/install with their own DirectX, thus installation of an older Version than already installed is not normally possible.
