On Debian the sound file is located here:

/usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga

and is provided by a package called "sound-theme-freedesktop":
https://packages.debian.org/unstable/main/sound-theme-freedesktop

By the way, I'm using PulseAudio, but the current libcanberra package
has no support for this option. Therefore, despite the fact that I'm
using an external audio interface, the sound produced by
canberra-gtk-play goes to the built-in speakers of my PC.

I see that in guix there is a package for pulseaudio. Any particular
reason for not enabling this sound framework option in libcanberra?
