I just upgraded to 18.04, and I noticed that the sound from my headphones, whether plugged into front or back port, was very crackling and slow/delayed. This issue didn't exist on 17.04/10. It also doesn't affect audio coming from HDMI via Radeon 560 GPU, just the headphone/onboard audio. The relevant device is:

00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)  

I tried a bunch of fixes for pulseaudio I found googling, including this one and this one. Neither of which helped.

I have found something that at least makes it listenable - changing "default-fragment-size-msec" from 25 to 5 in /etc/pulse/daemon.conf. It makes it much much better, but still a little crackly from time to time.

I've googled for 30 min or more now, and not finding anything else that seems recent and relevant, so wondering if I should maybe open a bug, or if there's something I'm overlooking here.

I had the same issue and killing pulseaudio fixed it for me. I'm not sure why it would get into a bad state, but restarting pulseaudio might be something to try.

Try

killall pulseaudio

Press Ctrl+Alt+T to go to a terminal and use your favourite editor to edit the file

nano /etc/pulse/default.pa

then find a line containing:

load-module module-udev-detect

modify this to become:

load-module module-udev-detect tsched=0

save and exit and you're all set!

If you have Firefox or Chrome open when the sound starts distorting. Shut them browsers down and test the sound again. If it has stopped, then you need to use a different web browser. I installed Vivaldi yesterday and I haven't had a problem since. There are many browsers to choose from.
