PulseAudio Is Streaming With An Excessive Latency.
https://centosfaq.org/centos/pulseaudio-is-streaming-with-an-excessive-latency/
PulseAudio is streaming with an excessive latency. Sound may be lost or quality degraded. To address that issue, upgrade the PulseAudio daemon to version 3.0, or disable the alternate sampling rate in its configuration I can find /etc/pulse/daemon.conf and its man page , but cannot figure out what to do.

https://juho.tykkala.fi/Pulseaudio-and-latency
Pulseaudio and latency If you are a Linux enthusiast and are playing fps games or record audio of some musical instrument then you have probably encountered issues with Pulseaudio latency. This blog post describes how to live with and manage Pulseaudio latency problems. For fast answer scroll directly to chapter Positive effect on latency as bellow is some leading …
[GUAC-427] Improve PulseAudio latency and bandwidth usage ...
https://jira.glyptodon.com/browse/GUAC-427
The current experimental PulseAudio support of libguac-client-vnc sends constant audio data over the wire even when audio isn't playing (it encodes silence), using excessive bandwidth. There is also wide variance in latency, with anywhere from < 1 second to 5+ seconds.
Very high CPU load due to PulseAudio latency …
https://github.com/mumble-voip/mumble/issues/1092
It seems that Mumble requests a very low latency from PulseAudio, resulting in very high CPU load. The PA process eats around 15% and Mumble 10% (+/- 3%). That's at idle and without pressing the PushToTalk key. The CPU is an i5 2500K run...
c++ - Increasing lag when transferring audio between ...
https://stackoverflow.com/questions/68580019/increasing-lag-when-transferring-audio-between-streams-with-pulseaudio
It's common trouble of sound application (with pulse audio, Direct Sound, etc.) with simultaneous input and output of the same data. The reason of lag may be something from list: The trouble is the result of lacking output data and sound device (rarely) has to add crack/silence/anysound. reads amount of data have been outputted (It can be ...
ALSA vs PulseAudio - Latency Concerns - Stack Overflow
https://stackoverflow.com/questions/29245583/alsa-vs-pulseaudio-latency-concerns
Additionally, it's to my understanding that ALSA is tied to Linux, but PulseAudio just acts as an abstraction layer on top of ALSA, and can work on other platforms. My conclusion is that ALSA would provide lower audio latency on most Linux systems, while my colleague contends that PulseAudio provides better (shorter) latency regardless.
PulseAudio: Audio Streams - freedesktop.org
https://freedesktop.org/software/pulseaudio/doxygen/streams.html
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. To get the raw data needed to calculate latencies, call pa_stream_get_timing_info ().
Audio delay when using pulseaudio and gstreamer ...
https://forums.raspberrypi.com/viewtopic.php?t=144967
You should be able to bring your gstreamer latency down to the order of 3 ms using alsa directly. I have clocked a GPIO soundcard down to 0.5 ms latency with low CPU load. As you crank up the CPU load, the required latency (block size) will increase. To lower the audio latency, work out how to reduce the block size which ALSA is using.
Minimizing Latency With pacat And Tvtime | Steven Elliott ...
https://selliott.org/node/59
I've modified pulseaudio so that it does not increase the latency beyond 50 msecs. The patch is here. It's experimental in the sense that there is probably a better way of solving the problem, but it works well enough for me. An alternative to pacat the …
