How to make the hardware beep sound with c++?

Answer 1

I tried most things here, none worked on my Ubuntu VM.

Here is a quick hack (credits goes here):

#include 
int main() {
  system("(speaker-test -t sine -f 1000)& pid=$!; sleep 1.0s; kill -9 $pid");
}

It will basically use system's speaker-test to produce the sound. This will not terminate quickly though, so the command runs it in background (the & part), then captures its process id (the pid=$1 part), sleeps for a certain amount that you can change (the sleep 1.0s part) and then it kills that process (the kill -9 $pid part).

sine is the sound produced. You can change it to pink or to a wav file.
