[Bug 207135] Re: pulseaudio uses too much CPU
My system was doing the same thing. It went from working properly one minute then broken for no reason. Very high CPU usage for pulseaudio, polkitd, dbus-daemon. PulseAudio sound was stuttering. Trying to edit the sound settings in the volume control was impossible because it kept losing the connection to PulseAudio. Syslog was full of thousands of this message repeated: [pulseaudio] alsa-mixer.c: Failed to set switch of IEC958: Operation not permitted I've had issues on this system where the sound output would randomly switch from analog out to some other method or even another device like HDMI which I don't use. I believe due to the plug auto-detection on the audio connector. So I unplugged, replugged, and jiggled the audio connector on the back of the computer and that fixed everything. I guess the plug was loose or the motherboard is buggy and doesn't properly detect when an analog plug is in the audio connector. This was causing pulseaudio to go haywire and hammer the system (not a surprise considering the history of that software). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/207135 Title: pulseaudio uses too much CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/207135/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 207135] Re: pulseaudio uses too much CPU
Maybe resample-method should be configurable through the sound settings applet? It's a huge waste to choose anything but the fastest algo when using pc speakers which I think is quite common. When using good headphones or a mid- to highend hifi you'd want to choose a good algo over a fast one obviously. When playing a given audio track through mplayer it consumes half the cpu compared to rhythmbox. Interestingly also the pulse process consumes half the cpu when using mplayer. I did some crude measurements with top and a few different values for resample-method. For these values I used mplayer -ao pulse from a tty without X running. src-sinc-best-quality (overkill, I know) uses between 70-100% and sound stutters with gaps of silence. src-sinc-medium-quality almost as much stutter as above, after a minute of playing it is almost enjoyable. 30% cpu. src-sinc-fastest uses about 8% cpu. ffmpeg/trivial/src-linear all use about 2-3%. -- pulseaudio uses too much CPU https://bugs.launchpad.net/bugs/207135 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 207135] Re: pulseaudio uses too much CPU
Confirmed here, too. Pulseaudio ate up to 50% of my 2.0 Ghz CPU, making both the video and the audio stutter in mplayer and totem. What's worse, you cannot stop pulseaudio daemon, and killing the process affects playback quality. The only solution is to completely remove pulseaudio from the system. In my opinion, if it's not fixed by the release it's better to disable pulseaudio by default. -- pulseaudio uses too much CPU https://bugs.launchpad.net/bugs/207135 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 207135] Re: pulseaudio uses too much CPU
If you are getting high CPU usage from pulse, change the resample method in /etc/pulse/daemon.conf to a less CPU intensive algorithm: resample-method = src-sinc-fastest See if this works for you. My CPU dropped from 2-5% CPU to pretty much below the background noise. Perhaps there needs to be a less high end default?

Re: [Bug 207135] Re: pulseaudio uses too much CPU
While that likely does lower CPU usage, I also believe it lowers the audio quality.

[Bug 207135] Re: pulseaudio uses too much CPU
After executing sudo /usr/bin/cpufreq-selector -g performance (so top isn't confused by lowered CPU frequency) I see pulseaudio using approximately 1% CPU when playing music which seems a bit much but not that troublesome.

[Bug 207135] Re: pulseaudio uses too much CPU
Hi, here on hardy beta, pulseaudio uses 5% while the system is idle. When I kill it, gnome-power-manager goes to 100% cpu usage! maybe this is a hint on who is causing the trouble? ... After restarting both pulseaudio and gnome-power-manager, I found that both are idle as they should. But when I unplug the power cable from my notebook, gnome-power-manager seems to play some audio. After that, the CPU usage goes up for pulseaudio. I hope this helps finding the problem.

Pulseaudio consumes only 0.5% if my cpu is running at 2.2Ghz, so I guess that's a reasonable cpu usage. -- pulseaudio uses too much CPU https://bugs.launchpad.net/bugs/207135 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
