PulseAudio Buffer Size Tests. March 7, 2011 kurtrtaylor. It has been a few weeks, but in my defense, I have been pretty busy testing and debugging in this new environment. As an assignee to the Linaro project, my first task was to figure out if increasing the buffer size would enable the ARM cpu to drop into a lower power state.

It is recommended to set this to (uint32_t) -1, which will initialize this to a value that is deemed sensible by the server. This should be set to a value that gives PulseAudio enough time to move the data from the per-stream playback buffer into the hardware playback buffer.

Pulseaudio is streambased. Both sourcesand sinksare present in terminology as well. Pulseaudio is also module based. As Pulseaudio is not kernel based and does not introduce new kernel modules, some other way of managing audio data streams should be present.

In case of a buffer underrun the read index is equal or larger than the write index. 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.
PulseAudio Configuration | Linux Sound
https://linuxsound.wordpress.com/2011/03/29/pulseaudio-configuration/
There are 3 places to change the configuration parameters and behavior of PulseAudio. system.pa/default.pa – startup script to specify module loading, etc, module parameters are passed here, more on that later. On Ubuntu, these files are installed in /etc/pulse. The system.pa startup script is used when PulseAudio is used in system-wide mode.
PulseAudio - Debian Wiki
https://wiki.debian.org/PulseAudio
PulseAudio is a network-capable sound server program. A sound server is a background process accepting sound input from one or more sources (processes, capture devices, etc.), that is able to mix and redirect those sources to one or more sinks (sound cards, remote network PulseAudio servers, or other processes).
