I can't seem to enable sound support when building Emacs from source:

Does Emacs support sound? no

It does not seem to be doing anything even if I do:

./configure --with-sound=yes

Looking at more of the output I see the lines:

checking for machine/soundcard.h... no
checking for sys/soundcard.h... no

I'm using macOS 10.13 with the latest version of Emacs.

Does this mean that Emacs cannot see/access my soundcard? My computer works fine with sound by the way.

Here is the configuration output after running ./configure:

Configured for 'x86_64-apple-darwin17.4.0'.

    Other than an occasional beep (e.g., beginning of buffer, or ending of buffer), I've never heard Emacs generate sound on OSX ... What types of sounds do you expect to hear? You can download a pre-built binary for OSX and see/hear what it generally should do: emacsformacosx.com

  • Hi. One of the packages I plan to use (pomidor.el) seems to need sound output as it generates the warning: Warning (emacs): This Emacs binary lacks sound support. Although now that you mention it, i do hear beeps. So I guess the backend for the package I am using just needs a specific program to play sound?

    It looks like someone has already been there and done that and has written a workaround for OSX with a library called play-sound.el: github.com/leoliu/play-sound-osx I recommend trying it by placing play-sound.el in your load-path and execute the snippet mentioned in the readme.md file and see if it works to your satisfaction. I found that by looking at line 108 of pomidor.el github.com/TatriX/pomidor/blob/master/pomidor.el#L108 and I got there by search for start-process, since that is what is normally used to execute an external application .... I also grepped

  • Ah! This seems to be the solution. I'll give it a check and update this question with an answer if it works. Thanks!

Package play-sound-osx does not work. But I found a solution:

(use-package pomidor
  :ensure t
  :bind (("<f12>" . pomidor))
  :config (setq
       pomidor-play-sound-file
       (lambda (file)
             (start-process "my-pomidor-play-sound"
                nil
                "afplay"
                file)))
  :hook (pomidor-mode . (lambda ()
                          (display-line-numbers-mode -1) ; Emacs 26.1+
                          (setq left-fringe-width 0 right-fringe-width 0)
                          (setq left-margin-width 2 right-margin-width 0)
                          ;; force fringe update
                          (set-window-buffer nil (current-buffer)))))
