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.

The size of this buffer needs to be chosen in a compromise between low latency and sensitivity for buffer overflows/underruns. ... A major problem with networked audio is the increased latency caused by the network. To remedy this, PulseAudio supports an advanced system of monitoring the current latency.

PulseAudio Configuration | Linux Sound

https://linuxsound.wordpress.com/2011/03/29/pulseaudio-configuration/

I did just that implementing a feature to add tsched buffer size to the configuration file. Late in the process, I discovered that it was already possible to pass it to the ALSA module, so I abandoned the additional code. Since it stumped me, I figured the configuration of PulseAudio might be somewhat confusing and could use a blog entry, hence ...

The minimum quantum (buffer size in samples) to use for pulseaudio clients. This value is calculated based on the frag and req/tlength for record and playback streams respectively and then clamped to this value to ensure no pulseaudio client asks for too small quantums. Lowering this value might decrease latency at the expense of more CPU usage.

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.
