Example of playing an audio file using libpulse

Branches:

• master: read audio file and play it.
• use_data_obj: the same audio file is converted to a ELF object file, and thus embeded into the binary executable.

Build & Run:

On the master branch:

./make.sh && ./a.out ~/bell.wav

On the use_data_obj branch:

./make.sh && ./a.out
