    I miss the old days when you could do
    ls -R / | aplay

    There’s no sudo, so it’s perfectly safe!!

      Can’t vouch for any other distro, but aplay is alive and well on Mint. The package that contains it — alsa-utils — seems to be a core dependency for Cinnamon, even.

      So basically, your example runs fine on my machine, screechy sounds and everything.

      There was a thing you could do with cat /dev/random into aplay, and get some fun “Music” but you needed some other parameters to get anything other than brown noise.

        Mine is basically the same, but since it pipes your filesystem layout into aplay instead of random bits, it’s not just brown noise.
        It plays you the song of your system.
        (also, it can damage your speakers, headphones and/or ears)
