Thanks for your bug report. This sounds more like a help request rather than a bug report, for future reference.

With respect to the sound functions, please uninstall the audio package. It is unmaintained and overrides the better supported functions in Octave.


octave:1> pkg uninstall audio
octave:2> soundsc (y)
## good audio playback ensues


With respect to the dirac function, yes it is in the symbolic package but it operates on symbolic variables, not on numeric values:


octave:1> pkg load symbolic
octave:2> syms x
octave:3> dirac (x)
ans = (sym) DiracDelta(x)


There is a numeric implementation of dirac in the specfun package, if that's what you want install specfun (although it is also not very well maintained).

Hi,
I am Jordi Lendínez from Spain. I try to use the functions sound and soundsc of the package audio in octave in xfce, but I recive this missage:


octave:3> soundsc(y)
error: sound.m: No command line utility found for sound playing
error: called from
    sound at line 108 column 5
    soundsc at line 52 column 5


Too I try to use the function "dirac" of the package symbolic, but I recive this message:

octave:3> dirac(1)
warning: the 'dirac' function belongs to the symbolic package from Octave Forge
but has not yet been implemented.

Please read <http://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
warning: called from
    __unimplemented__ at line 524 column 5
error: 'dirac' undefined near line 1 column 1


How can I solve these problems?

Thank you,

Jordi
