Audio server failed to start

[mickeymarse]

I have installed Sonic Pi version 4.5.1 via Flatpak (flathub) on my Linux Mint machine and, as I try to run is, I encounter this error:

Sorry, the Audio Server failed to start... Please try changing your default OS audio input & outputs. Note, the audio rate of the inputs & outputs must be the same. For the curious among you, Sonic Pi uses the SuperCollider Audio Server to generate its sounds. By default it will connect to your default system audio input and outputs. Unfortunately SuperCollider is having problems starting correctly. You can read the full error log below which should explain why. To fix this you can try changing your default operating system audio inputs and outputs (ensuring they have the same audio rate). Advanced Users - you may manually override this and further configure how SuperCollider boots by editing the file: /home/moka/.sonic-pi/config/audio-settings.toml SuperCollider Log Found 0 LADSPA plugins

Happy to share the logs.

install pipewire on linux mint. It's a Linux Mint problem.

install pipewire on linux mint. It's a Linux Mint problem.

It's already installed on my machine.

pipewire is already the newest version (0.3.48-1ubuntu3).
