I've got tired of beep not working, here is toot (cross-platform C C++), toot works. It simply tries to call different ways to produce a sine wave that might be present on your machine. __ __ / /_____ ____ / /_ / __/ __ \/ __ \/ __/ / /_/ /_/ / /_/ / /_ \__/\____/\____/\__/ a beep that beeps it's both a C/C++ library and a command line tool Windows OSX Linux BSD Solaris Minix Raspbian toot v1.0.9 [Jan 17, 2021] (c) 2017 - 2021 Guillaume Vareille http://ysengrin.com zlib licence https://github.com/vareille/toot git clone https://github.com/vareille/toot.git toot void toot(float aFrequency_Hz, int aLength_ms) ; Usage: toot [-f frequency_Hz] [-l length_ms] toot [-v] [--verbose] toot [-h] [--help] toot [--version] Default: toot -f 440. -l 400 Example: toot the release pane contains windows and osx executables make sure the volume is on (though some beeps may use the hardware speaker) if you can't adjust frequency / length (or if it doesn't beep) on osx: you can install sox http://macappstore.org/sox on unix: you can install pactl or speaker-test or sox If you know of any other way to reliably generate sine wave sound or beep on anykind of machine, I'll be happy to add them to toot.
