Terminology
- module : shared objet providing features (alsa, send audio to network …)
- sink : destination of audio stream (ex: alsa PCM device)
-
monitor : “virtual source” attached to every sink to capture audio (ex: save audio from youtube video to file)
client -> source -> sink module monitor client -> alsa -> pulse “card” -> alsa
Controlling pulse audio
- pacmd : command line to see config change parameters and load modules
- paman : pulse audio manager GUI allows you to see clients, modules, sinks …
Unresolved
- Why KDE in “Audio and Video” system settings lists hardware devices instead of just pointing to pulseaudio ?
