Pulseaudio And Latency | The Blog of Juho
https://juho.tykkala.fi/Pulseaudio-and-latency
There is current latency and configured latency present in every source and sink. You cannot configure latency directly but you can modify variables that affect latency positively. Modules and scheduling. Several other Pulseaudio modules (other than just module-alsa-card) are present in this example setup.

ALSA (like many other sound APIs) provides a ring buffer for samples to be played. The most common way to use this ring buffer is to keep it filled at all times. This implies that a sample that is written now is played only after all the other samples in the buffer have been played, i.e., the latency is proportional to the buffer's size.

When using PulseAudio on a 3rd Gen Ryzen CPU (Ryzen 7 3700X), PulseAudio defaults the ALSA latency to 100000us (100ms). Environment Without workaround: pa-info-out.txt With workaround: pa-info-out-2.txt Steps to reproduce Use PulseAudio on a 3rd Gen Ryzen CPU (audio device name is "Starship/Matisse HD Audio Controller Analog Stereo")
Latency doesn't work with PulseAudio on linux - Unix ...

To get an extra buffer you could add a null sink to use module-loobpack's latency_msec like so: pactl load-module module-null-sink sink_name=delayed pactl load-module module-loopback latency_msec=2000 source=delayed.monitor sink=alsa_output.pci-0000_00_1b.0.analog-stereo Then you have to combine the null sink with your bluetooth audio.
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.
[SOLVED] Zoom not detecting pulseaudio / Newbie Corner ...
https://bbs.archlinux.org/viewtopic.php?pid=2018119
Make sure lib32-libpulse is installed. If it is and zoom still uses ALSA devices by default select the "default" rather than a specifically named device as that should get bent to pulse via the config in pulseaudio-alsa. See the pinned comment on the AUR and make sure pulse is selected as the audio driver. Last edited by V1del (2022-01-24 07:58:23)

PulseAudio isn’t the only sound server for Linux. There’s also JACK, which is a recursive acronym for JACK Audio Connection Kit. Whereas PulseAudio was developed with the needs of general Linux users in mind, JACK is intended for DJs and audio professionals, providing real-time, low-latency connections for both audio and MIDI data.
