I've tried this with NO effect:
" down vote
Try sed 's/; default-sample-rate = 44100/default-sample-rate = 96000/g'
-i /etc/pulse/daemon.conf
That and sudo gedit /etc/pulse/default.pa and adding tsched=0 to load-
module module-udev-detect so it becomes load-module module-udev-detect
tsched=0 solved the issue for me.
For reference, the commands were put to my attention at
https://wiki.archlinux.org/index.php/PulseAudio#Glitches.2C_skips_or_crackling.";
