Sure, let's just say your “phone” is a computer system, then this same
generic advice applies.

Your operating system must have libsndfile and portaudio available and
working, and if Octave was built for your system with those libraries
present and enabled, then audio file I/O and sound card I/O should work.

If you didn't configure and compile Octave yourself, then a first step
would be to see if those features are present, try

  __have_feature__ ("PORTAUDIO")
  __have_feature__ ("SNDFILE")

in Octave. If PORTAUDIO returns false, then you don't have sound card
I/O. If SNDFILE returns false, then you don't have audio file I/O.
