org-clock-play-sound uses "aplay" to play sounds Source: https://github.com/emacs-mirror/emacs/blob/master/lisp/org/org-clock.el#L900-L916 aplay is available in the media-sound/alsa-utils package. However, it is not set as a dependency for Emacs, even though there exists an alsa USE flag.
The "alsa" USE flag controls a dependency on alsa-lib, which much be present at build time. alsa-utils sounds like an optional runtime dependency to me, which should not be coupled to a USE flag per Gentoo policy. https://projects.gentoo.org/qa/policy-guide/dependencies.html#pg0001
What floppym said. Things work fine without alsa-utils. There are countless optional runtime dependencies with explicit commands executed by some Emacs command. In addition, M-! which can execute an arbitrary shell command. We won't make use of optfeature.eclass either, because that would result in a very long (and probably never complete) list.

I see. I completely understand. Having said that, were not it for this stack exchange question*1, I never would have found out that I neede aplay. *1: https://emacs.stackexchange.com/questions/67956/trying-to-set-org-clock-sound-for-org-timer Would it be fair to add an optfeature message to the org-mode gentoo package? The PR was org-mode specific after all. - Best regards

I fear the same argument applies for org-more that applies for Emacs. As a matter of fact, we already have a README.gentoo for app-emacs/org-mode saying: local DOC_CONTENTS="Org mode has a large variety of run-time dependencies, so you may have to install one or more additional packages. A non-exhaustive list of these dependencies may be found at <http://orgmode.org/worg/org-dependencies.html>." (Interestingly, the upstream list doesn't contain aplay.)

Noted! Thank you very much for the reply. Maybe I'll try to mention aplay to the org-mode devs!
