Vala PulseAudio playback Example - GNOME
https://wiki.gnome.org/Projects/Vala/PulseAudioSamples
Vala PulseAudio playback Example. This is a simple test example using pulseaudio's asynchronous API. It opens a connection to the audio device and plays a sine wave. Notice that you have to check the state on a context to see that it is ready BEFORE attempting to do stream.connect_playback (); Get the libpulse vapi's at http://www.pulseaudio.org/ or using:
PulseAudio/Examples - ArchWiki - Arch Linux

No replacement of ALSA's default, no playing with mixer levels, nothing but record/playback. Also make sure pulseaudio-alsa is not installed so standard ALSA clients do not default to pulse. ... such as dynamically reacting to changes in the PulseAudio server, for example when a headset or a webcam is plugged in or unplugged.
Async Playback – Developer Documentation – PulseAudio
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/Developer/Clients/Samples/AsyncPlayback/
This code is not made by any PulseAudio developer. It may not be best practice, but it seems to work and could be used as a start for a playback application that uses the async API. This simple application plays a constant note and uses a low latency setup (20 ms) that should be suitable for games.

PulseAudio - Official Kodi Wiki
https://kodi.wiki/view/PulseAudio
PulseAudio allows normal video & audio playback in XBMC while at the same time allowing the user to get audio in their browser or other applications. It also allows Kodi playback of video or audio to be paused in order to run a game, Skype or similar. Kodi is set to only use PulseAudio if you have installed it and running.
PulseAudio: Audio Streams - freedesktop.org
https://freedesktop.org/software/pulseaudio/doxygen/streams.html
Unless the prebuf value is 0, PulseAudio will temporarily pause playback in such a case, and wait until the buffer is filled up to prebuf bytes again. If prebuf is 0, the read index may be larger than the write index, in which case silence is played. If the application writes data to indexes lower than the read index, the data is immediately lost.
Audio APIs, Part 2: Pulseaudio / Linux - Bastibe.de

In the end, I followed some marginally-related example on the internet to get to that point, because the two examples provided by PulseAudio don't even use the asynchronous API. Perhaps I am missing something, but it strikes me as strange that an API meant for audio recording and playback would not include an example that plays back and records ...
How do you use both Pulse Audio and Alsa? - Ask Ubuntu
https://askubuntu.com/questions/147981/how-do-you-use-both-pulse-audio-and-alsa
ALSA is the kernel level sound mixer, it manages your sound card directly. ALSA is a crap (seriously) and it can handle a few (sometimes just one) channel. PulseAudio is a software mixer, on top of the userland (like you'd run an app). When it runs, it uses Alsa's channel and manages EVERY mixing stuff, devices, network devices, everything by ...
