How to get rid of stuttering in video and audio on Kubuntu 20.04?

Question

linux

There is Kubuntu 20.04. Slows down video and sound. In the system player, in browsers in applications, etc. Previously, sometimes a similar problem appeared, but a reboot helped. The problem has now become permanent. Tried different PulseAudio settings from the net. But, it did not give any result.

Maybe someone else has come across something similar. Tell me how to solve this problem?

Answer 1

Well, for example, I treated stuttering in civ5 like this:
/etc/pulse/daemon.conf
default-fragments = 5
default-fragment-size-msec = 2
plus, set the correct values ​​for your sound. maps, example:
default-sample-format = float32le
default-sample-rate = 96000
alternate-sample-rate = 48000
