Pulseaudio on Photon OS on WSL2 - dcasota/photonos-scripts GitHub Wiki

Pulseaudio on WSL2 for non-preferred Linux distribution is a manual process.

On Windows

Download Pulseaudio and install it to e.g. c:\pulse.

Create a subdirectory c:\pulse\etc\pulse and copy the content of default config filesdirectory into it.

Navigate to C:\pulse\etc\pulse. Edit default.pa using a text editor (e.g., Notepad). Find the line:

#load-module module-native-protocol-tcp

Uncomment it (remove the #) and modify it to allow connections from WSL2's IP range:

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;172.16.0.0/12

See https://grok.com/share/bGVnYWN5_c7a1d0a7-174e-4c6c-b5e3-9e7809ddae1a tun run Pulseuadio as a service.

Start pulseaudio.

On Photon OS on WSL2

On Ubuntu, you can use sudo apt install pulseaudio pulseaudio-utils.
On Photon OS, there is no Pulseaudio package. Here a recipe to build it.

sudo make
sudo make install

After that, set the PulseAudio Server Address: WSL2 assigns dynamic IP addresses, so retrieve the Windows host IP from /etc/resolv.conf. To make this persistent, add the following to your shell configuration file (e.g., ~/.bashrc for Bash):

export HOST_IP=$(ip route | awk '/^default/{print $3}')
export PULSE_SERVER=tcp:$HOST_IP

Then, save and reload the sell:

source ~/.bashrc

This ensures the PULSE_SERVER environment variable points to the Windows host’s IP.

Restart Photon OS on WSL2.

On Windows, start Pulseaudio.

On Photon OS, login and test pulseaudio.
