The Windows Subsystem for Linux Installation Guide for Windows 10 are pretty staightforward, but let's summarize them anyway. As an administrator in a PowerShell window:

cd c:\temp
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Download[1] a Linux distribution, for example Ubuntu 18.04:

Invoke-WebRequest -Uri -OutFile Ubuntu.appx -UseBasicParsing

Install with:

Add-AppPackage .\Ubuntu.appx

The noisy terminal bell can be disabled[2] via /etc/inputrc:

set bell-style none


For some reason we needed sound support in our WLS environment. Another blog explained how to do this[3] but we only need sound on the command line, so we can omit some parts. The important steps are:

  • Download a precompiled pulseaudio binary from
  • Extract and edit a two files before we can start it:
load-module module-waveout sink_name=output source_name=input
load-module module-waveout sink_name=output source_name=input record=0

#load-module module-native-protocol-tcp
load-module module-native-protocol-tcp auth-ip-acl=
; exit-idle-time = 20
exit-idle-time = -1
  • With that, pulseaudio.exe should be able to start and will now listen on localhost
  • For our needs, all we needed to do was to point our music program (in WSL) to the Pulseaudio server (running in Windows):
export PULSE_SERVER=tcp:
mpg123 file.mp3

Other programs may need other hints to connect to the Pulseaudio server though.
