This tutorial is going to explain how to fix pulseaudio completely and the video/audio playbackissues of V ! "edia Player# $ope this helps# The time scheduling function is still a bit bugged

and gives off audio issues % noticed# &o unless you want ' seconds of chopping( skipping( andgarbling each time you start an audio app( we)re not going to use it# *lso( if you)re fine with that(can live with the issue and like how it makes Pulse*udio less !P+ intensive( then skip the stepwhere we disable time scheduling in this tutorial# ,-ou can disable it later if needed after you)redone.&o let)s get started#

Fixing PulseAudio: "e #ant no less thanperfe$tion%resh off of an upgraded install % noticed many things were broken with the audio( so we)regoing to uninstall Pulse*udio first#
