Updated PKGBUILD to build headsetcontrol with both shared and static library. What changed:

• Add staticlibs to options to keep both static and shared library.
• Switch to use annotated tag instead. Otherwise, the continuous tag is used.
• Add -ffat-lto-objects to CXXFLAGS. Otherwise, the static library is unusable.
• No need to manually generate udev rules anymore.

🛠️ After running paru -Syu --devel, the update to headsetcontrol-git (2.7.0.r1.gbd8aed3-2) appears in the AUR helper GUI, but when building, the version reverts to continuous.r0.g12d8483-1.

This seems to happen because the Git repository hasn't actually advanced — pkgver() resolves to the same commit as before (g12d8483), so the installed version doesn’t change.

@MarsSeed I've updated the package to include your proposed changes.

(I have to say, I was quite surprised to be notified here and and just found out I'm now listed as maintainer of this package for some reason.)

Thanks to @s3lph for the solution. It works!

However, I would suggest using /usr/lib/udev/rules.d/ instead of /etc/udev/rules.d/ since packages should place their rules there.

The upstream recently changed their approach to udev rules: Previously they shipped a precomiled list of rules, now they are generated dynamically. Please update the PKGBUILD accordingly. E.g. something like this:
