sound - PulseAudio Loopback Latency - Ask Ubuntu
https://askubuntu.com/questions/491825/pulseaudio-loopback-latency
Sometime ago I was able to loopback my guitar to the speakers without noticeable delay, so pulseaudio supports that, but I remember having trouble with delays less than 10ms. My suggestions are . to review the command parameters ; use a bigger delay ; test each loopback separately and ; ask directly pulseaudio developers for instructions.

I've found information, that to play sound from input device I need to load loopback pulseaudio module and I did so: pactl load-module module-loopback source="bluez_source.2C_FF_EE_2D_22_51" sink="alsa_output.platform-sunxi-codec.analog-stereo". Such command creates two loopbacks, one in playback and one in recording.

PulseAudio Loopback. The goal behind this switch is to allow a very flexible whole home audio system based upon PulseAudio. For example, for a system with a 7.1 surround sound card, and 3 instances of MPD running, it is possible to quickly route the output of any MPD instance to any of the 8 possible (4 stereo) channels on the sound card, by loading/unloading a loopback module.

If "true", PulseAudio will slightly delay hardware volume changes in order to synchronize the changes with software volume changes. fixed_latency_range A boolean. Normally when there's an alsa underrun or overrun, and timer-based scheduling is used, the alsa sink or source will raise the minimum latency that applications can get to avoid ...
Audio Loopback Recording with PulseAudio - Debian Wiki

Pulseaudio provides us with the means to easily create an audio loopback device that allows us to record sounds produced by our system as if they were being redirected into the microphone. This could be useful for screen recording sessions where you want to capture the audio as it is produced instead of just setting an external microphone next to your speaker.

After that we need to load the pulseaudio module for the loopback device. pactl load-module module-loopback latency_msec=1000. That would load the loopback module with a delay of 1000 ms (1 second). You can set that value lower (like 1 ms) if you want to hear yourself realtime or a higher value if you get irritated by hearing yourself.
