I’d been having freezes and crashes with Ubuntu 18.04, especially while playing audio/video from the internet, so I upgraded it to 20.04, and then to 22.04, hoping this would have been sorted out. It hasn’t. The behaviour is this: everything stalls, the screen freezes mouse or keyboard do not respond, and curiously, the audio that was playing (it might be someone I’m talking to on Skype, or from a YouTube video) keeps repeating a 1-second loop like a broken record (“like a broken rec− like a broken rec− like a broken rec− like broken a rec− like broken a rec−” &c). Any ideas what causes this and how to fix it? My kernel is: 5.15.0-53-lowlatency

The problem is related to graphics driver compatibility. I had a very similar problem and was struggling for few months but finally adding a /etc/X11/xorg.conf.d/20-intel.conf did the magic. I had an Intel integrated graphics so Ubuntu driver manager showed "No drivers needed".

Section "Device"
 Identifier "Intel Graphics"
 Driver "intel"
EndSection

This would make sure your graphics drivers are loaded correctly.

The Arch Linux Intel graphics wiki page is also very helpful.

Note: You could have other graphics drivers so please make changes accordingly. This would also help people looking for solution and struggling for months as it is very common problem with Intel integrated graphics drivers and Ubuntu.

Don't know if you still have this issue or not. But I fixed mine by turning off the power management of wifi. first, try to find the power management is on or off.

iwconfig

if Power Management: on

open your network manager power management option by

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

you'll find

wifi.powersave = 3

change this 3 to 2.

now reboot your PC then check again

iwconfig

Power Management:off

this should solve the problem.
