Actual behavior

Fixed the same problem on my WSL/Arch by deleting the existing PULSE_SERVER environment variable from my .zshrc and reloading the shell.

Works fine here in WSL/Manjaro after deleting the existing PULSE_SERVER environment variable

[spronovo]

We run our PulseAudio server in the system distro on a socket shared back to your user distro located at /mnt/wslg/PulseServer. As part of WSL init and before your distro start up, we pre-initialize PULSE_SERVER environment variable to reference that location. If you have setting that override that environment variable, it will break audio.

If you restore it as below, audio should start working again (you'll have to restart the app too i believe).

export PULSE_SERVER=/mnt/wslg/PulseServer

So you'll want to avoid changing the value of PULSE_SERVER that we prepopulate, so the suggestion above of removing that this variable from things like your .zshrc are correct.

Thanks you both for the update, however, while good to know, I do not believe that is my particular issue;

luke@duskwood:~$ env | grep PULSE
PULSE_SERVER=/mnt/wslg/PulseServer
luke@duskwood:~$ vlc
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
shm_open() failed: No such file or directory
[0000000002194dd8] pulse audio output error: PulseAudio server connection failure: Protocol error
[000000000209a148] core libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

It looks like the env PULSE_SERVER has been set correctly and no other attempts to changes it that I can find in various startup scripts etc. However, as you can see pulse audio still appears to be failing. Let me know if more info can help with the diagnosing etc.

Cheers,

@lduguid what WSL distro are you using? Does audio work in other app, like say firefox? Or broken across the board?

[lduguid]

At the time it was Ubuntu 16.04. I also tested firefox and navigated to youtube, also no sound. I did not capture the errors with firefox at the time. Unfortunately, yesterday I required this laptop for some work related tasks and as the dev windows preview was a little unstable in other respects (non-wsl related) and slow, I reverted back to Microsoft Windows [Version 10.0.19042.928] for now. I will get back to testing this in about a weeks time. I also have Ubuntu 20.x on that machine, I will test with it as well. If there are new insights I will comment here. Thanking you.

Had this problem with Debian on WSL2 using wslg, no audio was coming from firefox or google-chrome.

It was simply fixed by installing pulseaudio "sudo apt intsall pulseaudio"

It was simply fixed by installing pulseaudio "sudo apt intsall pulseaudio"

Fixed this problem with "yay pulseaudio" on Arch.
Thanks!
