I'm working through a Linux textbook, and it's telling me about devices. It says that if I send the appropriate output to
/dev/dsp, then it will play a sound. The example is
cat file.wav > /dev/dsp, where file.wav is just any .wav file.
When I do this I get permission denied. If I run this with sudo I still get permission denied. If I
su first, no sound plays.
Why do I get permission denied with
sudo? Why does no sound play even with
