From 6cdc2d189cb60a9d13e2d975b3fdb12eb00885cc Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 9 Nov 2018 15:20:32 +0100 Subject: pulseaudio: process audio data in smaller chunks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The rate of pulseaudio absorbing the audio stream is used to control the the rate of the guests audio stream. When the emulated hardware uses small chunks (like intel-hda does) we need small chunks on the audio backend side too, otherwise that feedback loop doesn't work very well.
