In ubuntu, after a while, the sound jams if you do not touch the mouse. How to fix?

Question

linux

Installed ubuntu 16.04 x32. Installed the proprietary driver for the video card. Everything was fine, but then I noticed that if you turn on the music and do not touch anything, then after ~ 30 seconds. she just eats. After pulling the mouse, it continues again. And if you just leave the computer ~ 5 minutes. then the system completely freezes, and you have to reboot the system. Tell me how to fix this?

Answer 1

Judging by the "Core temperature above threshold, cpu clock throttled" in the log, your processor overheats and resets the frequencies, after which there may not be enough frequency for smooth sound playback. After cooling down, the frequencies return to "Core temperature/speed normal" and the sound should work normally. If the computer freezes completely, then I can assume that it is overheating.
Look at what processes are eating a lot of CPU, for example, in the GNOME system monitor (System Monitor if the Russian interface).

Answer 2

A real Linuxoid would automate the twitching of the mouse every 30 seconds.
