Pipewire: The How, What and Why of Audio on (Embedded) Linux
Understanding the audio ecosystem on Linux is not straight-forward.
Alsa, who? Pulse-audio, what? And what is this Pipewire everyone keeps talking about?
In this presentation, we want to provide a brief overview of the audio subsystem on Linux, looking at libraries provided by the kernel and how to work with it when writing user-space applications. Our goal is to clarify some of the confusion around the different libraries and tools and empower people to embrace the ecosystem instead of being intimidated by it.
Lastly, we would like to give a hands-on introduction to Pipewire, a new audio server shipped in many Linux distributions. We will cover how Pipewire works and how we use it professionally on our embedded linux platform. We will also show how to configure, introspect and debug the pipewire daemon, all the way to creating DSP chains by simply writing a small config file.
