18.04: Sound crackling - pulseaudio CPU usage jumps












0















I noticed that when I do some action, sound starts crackling and mouse starts freezing for a short amount of time (like 1 sec).



This happens, for example, when I scroll page on browser (not just Chrome) or when I start some program, sometimes when I type on keyboard.



Everytime this happens, CPU usage of



/usr/bin/pulseaudio --start --log-target=syslog



jumps to 30% - 60% for a moment (like 1 sec).



Do you know what to do to fix this?

  • I'd try to diagnose the problem before attempting to fix it. For example, the syslog might have some info, also, the output of aplay -l seems relevant. I am not sure the hardware specs you've highlighted are relevant though.

  • @mikewhatever Thank you Mike. I've added output of aplay -l and tail of syslog to the end of the question. I've noticed crackling at 19:36:50 but there is nothing in syslog with that or close to that time.

I noticed that when I do some action, sound starts crackling and mouse starts freezing for a short amount of time (like 1 sec).



This happens, for example, when I scroll page on browser (not just Chrome) or when I start some program, sometimes when I type on keyboard.



Everytime this happens, CPU usage of



/usr/bin/pulseaudio --start --log-target=syslog



jumps to 30% - 60% for a moment (like 1 sec).



Do you know what to do to fix this?



EDIT

  • I'd try to diagnose the problem before attempting to fix it. For example, the syslog might have some info, also, the output of aplay -l seems relevant. I am not sure the hardware specs you've highlighted are relevant though.

  • @mikewhatever Thank you Mike. I've added output of aplay -l and tail of syslog to the end of the question. I've noticed crackling at 19:36:50 but there is nothing in syslog with that or close to that time.

I noticed that when I do some action, sound starts crackling and mouse starts freezing for a short amount of time (like 1 sec).



This happens, for example, when I scroll page on browser (not just Chrome) or when I start some program, sometimes when I type on keyboard.



Everytime this happens, CPU usage of



/usr/bin/pulseaudio --start --log-target=syslog



jumps to 30% - 60% for a moment (like 1 sec).



Do you know what to do to fix this?

pulseaudio performance cpu







share|improve this question
















I noticed that when I do some action, sound starts crackling and mouse starts freezing for a short amount of time (like 1 sec).



This happens, for example, when I scroll page on browser (not just Chrome) or when I start some program, sometimes when I type on keyboard.



Everytime this happens, CPU usage of



/usr/bin/pulseaudio --start --log-target=syslog



jumps to 30% - 60% for a moment (like 1 sec).



Do you know what to do to fix this?

  • I'd try to diagnose the problem before attempting to fix it. For example, the syslog might have some info, also, the output of aplay -l seems relevant. I am not sure the hardware specs you've highlighted are relevant though.

  • @mikewhatever Thank you Mike. I've added output of aplay -l and tail of syslog to the end of the question. I've noticed crackling at 19:36:50 but there is nothing in syslog with that or close to that time.
