sunshine cannot detect a running pulseaudio instance by default.

[dElogics]

Is there an existing issue for this?

• I have searched the existing issues

Is your issue described in the documentation?

• I have read the documentation

Is your issue present in the latest beta/pre-release?

I'm too lazy to test

Describe the Bug

sunshine fails to detect an existing running pulseaudio instance as a result it launched another instances which cannot grab the hardware audio device because an existing pulseaudio instance is already using it. the newly launched pulseaudio instance tried to repeatedly grab the audio device resulting in 100% CPU utilization. It also results in sunshine crashing after the client (moonlight exits).

If sunshine is started with PULSE_SERVER=/run/user/1000/pulse/native, a new pulseaudio instance is not launched neither sunshine ever crashes.

This is wayland KDE session within no login/display manager. pulseaudio is launched by KDE.

Expected Behavior

No response

Additional Context

I don't think you guys have made any changes to the pulseaudio code since 0.23.1. In case you have, then you ask me to test again the latest by cloning from git (gentoo package manager supports that), however it requires upgrading boost because of which it will trigger a rebuild of many many heavy packages (including libreoffice).

sunshine already links against the system's pulseaudio --

ldd /usr/bin/sunshine | grep pulse
libpulse.so.0 => /usr/lib64/libpulse.so.0 (0x00007fcb54741000)
