Audio stuttering in Ubuntu 18.04
In my case (ubuntu 18.04 on alienware m15 laptop) the sound stuttered and glitched randomly with any sound source. Disabling the Wi-Fi is not an option for me, I have stumbled upon a blog post that suggests the problem is in pulseaudio's realtime-scheduling setting, solution from there helped me fix the problem:
- Turn off realtime scheduling - edit
/etc/pulse/daemon.pa(I had/etc/pulse/daemon.conf):
; realtime-scheduling = yes
realtime-scheduling = no
- Restart pulseaudio:
pulseaudio --kill
pulseaudio --start

This turns out to be a bug as suggested by GoodGuyNick in the question's comments. The workaround is to disable Wi-Fi when not in use.
Are you using laptop with Realtek RTL8188EE wireless network adapter? Because there is a bug in kernel which causes audio stutter if your wifi enabled and you are not connected to any wifi network.
