This is a nice idea. Unfortunately alarm() makes no noise on my
system---I guess it's some small configuration issue---, but this
reminds me of system(). So one can do something similar:

<<done,echo=FALSE>>=
system("play /tmp/03Miserere.ogg")
@

It makes the LyX status bar go crazy, but otherwise seems to work just fine.

I'm wondering: does LyX have a LFUN_SYSTEM_COMMAND or similar that
would allow to execute arbitrary system commands?
