   That is irrelevant, the basic problem is the same.   
      
   In my machine, "root" can not play sound, no permission:   
      
      
   Telcontar:~ # play abitsilly.wav   
   play FAIL formats: can't open output file `default': can not open audio   
   device: Connection refused   
   Telcontar:~ # aplay abitsilly.wav   
   ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave   
   aplay: main:828: audio open error: No such file or directory   
   Telcontar:~ # paplay abitsilly.wav   
   Connection failure: Connection refused   
   pa_context_connect() failed: Connection refused   
   Telcontar:~ #   
      
   Telcontar:~/ThingsNeededForBoot # vlc abitsilly.wav   
   VLC is not supposed to be run as root. Sorry.   
   If you need to use real-time priorities and/or privileged TCP ports   
   you can use vlc-wrapper (make sure it is Set-UID root and   
   cannot be run by non-trusted users first).   
   Telcontar:~/ThingsNeededForBoot # mplayer abitsilly.wav   
   MPlayer 1.2.r38170-Packman-7 (C) 2000-2020 MPlayer Team   
   ...   
      
   but no sound.   
      
      
      
      
   Telcontar:~ # cat hal9.au > /dev/audio   
   Telcontar:~ #   
      
      
   and no sound.   
      
      
   cer@Telcontar:~> play /usr/share/sounds/Mine/abitsilly.wav   
      
   /usr/share/sounds/Mine/abitsilly.wav:

   Done.   
   cer@Telcontar:~>   
      
   (and we have sound)   
      
      
      
   Ok, so perhaps use "su - desktopuser -c playsomething", but at least I,   
   I want to play things before the desktop is up with a user.   
      
      
      
      
   Cron (or timer) is worse: no terminal assigned, so echoing the bell   
   character will not sound.   
      
   cer@Telcontar:~> whatis bell   
   bell (n)             - Ring a display's bell   
   cer@Telcontar:~>   
      
      
      
   The first step, if using "pulse", would be to run it as independent daemon.

   Cheers, Carlos.
