Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

The Alarm plugin is only available with the GTK version.
Make sure to use "--enable-gtk" also for audacious-plugins.

See I did that, and compiled with gtk, but it still says that alarm is disabled when I compile the plugins.

You said you have compiled Audacious with GTK support, but did you also use "./configure --enable-gtk" for the plugins?
The output of configure may also help, please attach it here.

Oh I'm sorry I just noticed that you said audacious-plugins also has --enable-gtk, I'll try that!

Okay so compiling with --enable-gtk SAYS it enables the alarm, but I can't find it under plugins. Attached are the terminal outputs.

You are probably still using the default Qt interface.
If you compile Audacious with GTK and Qt support, you need to start it explicitly with "-G" or "--gtk".
Alternatively use "--disable-qt" for the configure script. Again for both Audacious and the plugins.

Oh I see! I didn't realize that I had to launch it separately with gtk, thank you so much that helps immensely!
