Regarding latency of pulseaudio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


What is the latency and configured latency that is being displayed in pulseaudio via pactl list sinks?

It is observed that these parameters value is less in pulseaudio version 9 and more in pulseaudio version 15 for module-alsa-sink,

checked while playing same stream using paplay.

Example:  version 9 -  Latency: 22429 usec, configured 23219 usec

                  version 15 - Latency: 79711 usec, configured 92879 usec

It's observed that values are too high in pulseaudio 15 version.

is this the actual latency introduced by the module-alsa-sink? or overall pulseaudio ?

Is there a way to measure the latency introduced by pulseaudio in a file playback?
