Thanks for your work! Recently, I added some minor shortcut tricks to bring a more convenient way to run the PulseAudio. Instead of registering the PulseAudio, I created a shortcut for wsl.exe with the below arguments.

%WINDIR%\System32\wsl.exe -d Ubuntu-20.04 -- sudo service dbus start && sudo service xrdp start && pulseaudio & mstsc.exe /v:$(hostname -I)

Shortly, Microsoft will release their own Wayland implementation. But before that, I'm very excited that my script is helped your works. It's my pleasure. ;-)

The first error says that you don't have write permission in the directory where you're running configure. I don't know if that's normal for whatever operating system you're running, and determining that and fixing it is out of scope for this gist.

The cleanest and safest way I can think of to make these instructions work for you is to

  1. create a directory in your home directory like mkdir -p ~/pulseaudio, then
  2. start following the instructions above from line 22, replacing /tmp with ~/pulseaudio everywhere.
