Im inclined to make it unconditional (libcanberra-gtk3 isn't required but libcanberra is). So from a no X perspective this won't block disabling X elsewhere. It’s not really required in the sense of “program doesn’t work without it”. I’m running without it right now (I built with USE=-X, then preserved-rebuilt after unmerging), and pavucontrol still works fine. I actually don’t know exactly what it added; “system sounds” is still a controllable volume knob even without it.

I currently don’t have it on this box, and pavucontrol is fine. Created attachment 920545 [details, diff]
Make libcanberra an option (not upstreamable as is)
I'm now considering just disabling it. I'm not sure if its something about my environment or if the feature is broken. I think there is supposed to be a notification sound when the audio level changes?
It looks like there is code in src/sinkwidget.cc that plays a sound of some sort via libcanberra when you change the volume of a sink, if libcanberra is enabled. Not actually sure if it works or not, but the code is there, trying. I've now found the difference. Its *very* minor. When you change the volume for a sink in "Output Devices" (not any other volume!) it makes a sound. |
The ebuild for pavucontrol depends on libcanberra conditionally on USE=X. However, that information is never passed to the pavucontrol build system; instead, the build system autodetects whether libcanberra is present or not, and thus will end up linking to it even if USE=-X. This results in an @preserved-rebuild prompt if one unmerges libcanberra. Reproducible: Always Steps to Reproduce: 1. Emerge pavucontrol with USE=X 2. Remerge pavucontrol with USE=-X 3. Unmerge libcanberra and libcanberra-gtk3 Actual Results: No @preserved-rebuild prompt, pavucontrol binary not linked to libcanberra.so Expected Results: @preserved-rebuild prompt, pavucontrol binary still linked to libcanberra.so $ emerge --info media-sound/pavucontrol Portage 3.0.66.1 (python 3.12.9-final-0, default/linux/amd64/23.0/systemd, gcc-14, glibc-2.40-r8, 6.12.16-gentoo x86_64)
