    pulseaudio is running at 100%

    pulseaudio is running at 100%. no audio is being played. if i do play audio it plays fine and the 100% usage continues. is this one of those "issues" it has with "system mode"?

    Someday, pulse audio will be stable. They've only had 10 yrs. It is much better now than it was 5 yrs ago, but still far from perfect.

    Kill the pulseaudio process. It should automatically restart. If it doesn't, then manually restart it. These processes are owned by your userid.

    Re: pulseaudio is running at 100%

    in system mode there is a single central process owned by user pulse and that is the one that is running at 100% which is why i'm wondering about system mode. when i play audio, this process, when it is not doing the 100% thing, jumps to about 8%. no other processes run. the individual userid process don't get started even for playing audio.

    Re: pulseaudio is running at 100%

    at this moment nothing is playing any audio at all. only one process is running pulseaufio. it is owned by user name pulse. it is using 18.8% of CPU. i have no ideas what it is doing.

    edit:

    i started playing a 16 minute audio file and CPU usage went up to 19.1%

    there is no other way to keep the music playing as i switch to other userids (typically about 18 userids logged in and typically about 6 in busy use).

    what my initial post is asking about is why does it sometimes use so much CPU to do nothing (no audio is playing).

    audio works fine all the time. these steps are assuming one is not using system mode and will end system mode in step 1 making all further steps unable to diagnose any issue with system mode. since a reboot is part of the steps i cannot do that for a few hours due to things i have running that don't have an ability to resume. not that i would do them.
