View Full Version : [ubuntu] hp2133 pulseaudio stuttering and high cpu
May 24th, 2011, 02:55 PM
I have tested maverick and linux mint 10 in hp2133. Looks like there is a problem with pulseaudio. When using a recording application (gnome-sound-recorder or skype) and internal mic, pulseaudio eats all available cpu (cpu running 100%) and the sound is stuttering. Arecord and aplay works fine without any problems so the problem seems to be related to pulseaudio. I can get a little bit help when using tsched=0 setting, there is less stuttering, but pulseaudio still uses about 26% of cpu, which is way too much for this low end cpu.
I'm running out of ideas. Anyone having any suggestions?

Over 2 years on and I am still having this problem. Pulseaudio has rendered this machine almost useless.
I gave up on Skype and tried Ekiga/Empathy but Pulseaudio ruins that too. I tried all sort of alsa fixes here are dozens of "solutions" on the net but none work fully.
How do I stop it from grabbing so much cpu ?

Why is this listed as fixed even though it clearly isn't ?
