Wild guess. Libspa version has changed and thus its path too. You will have to put (probsbly new version) of aac.so file to new libspa directory.
Yeah, it might require new one if dependencies have been changed.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Title misleading: you did not lose "the" AAC codec after upgrading.
You're asking for advice regarding a custom solution that stopped working after the upgrade.

How is the title misleading? The AAC codec had no issues working on Bookworm but not on Trixie ie I lost the ability to use it.

Debian does not package the AAC codec due to licensing issues hence why we’re forced to find these “custom” solutions.
It's just that the title could be misread as a complaint about dist-upgrade being less than reliable. Which it isn't.

Not true. I'm listening to AAC encoded music right now. No extra repositories were even required.

Interesting, going over the documentation from the Debian Wiki they even say it’s not distributed in their repo’s?
The AAC codec is unavailable in Debian 12 bookworm.
In the case of PipeWire its support (see the 1021370 request) requires the non-free libfdk-aac2 package. A request to provide free version of the package was declined due to possible licensing and patent issues (see 981285). The only workaround is to build the AAC Bluetooth plugin from sources.
PulseAudio-16 (Debian 12 bookworm) does not support AAC. Despite necessary patches from the gstreamer merge request !1172 are applied to gstreamer1.0-fdkaac, there are pending changes in the PulseAudio Bluetooth plugin, see the upstream merge request !473.
I couldn’t find instructions from Bluez to install the source and I didnt want to risk breaking my current install by just guessing hence why I went with the solution posted on Reddit.
It seems you're talking about something specific to bluetooth yet you made a very broad statement about "The AAC codec" earlier. As with your title: Be precise.
Well, ACC is Apple, so go ogg onstead... ;-)
