How do I make my pc speaker beep in WSL?

Question

How can I make ring the bell from command line using WSL (2)?

I tried:

beep
echo -ne '\007'
echo -e "\a"

I have set bellstyle none in /etc/inputrc.

Using Ubuntu 18.04 image.

In WSL Ubuntu or Alpine with default path setup, you can depend on .net's Console.Beep method:

powershell.exe '[console]::beep(261.6,700)'

It makes a handy alias for etc/profile or ~/.bashrc:

alias bloop="powershell.exe '[console]::beep(261.6,700)'"

Define a helper function to create multiple tones:

_beep () {
  powershell.exe "[console]::beep($1,$2)"
}

alias bleep="_beep 1000 800"  # A strong bleep (for profanity)
alias  beep="_beep 2000 300"  # Quick yet noticeable beep
alias  blip="_beep 4000  80"  # A less distracting blip

Example: Blip on success, but bleep on failure:

make && blip || bleep
