The only other process having similar CPU use is X11. We should investigate this.
what version of pulse and the plugin do you have? I dont have any problems with it. My laptop has ~4days of uptime and the the plugin has 5 seconds of CPU time. media-sound/pulseaudio-8.0 xfce-extra/xfce4-pulseaudio-plugin-0.2.3
Same pulseaudio, but plugin is 0.2.4. I'll test the earlier one.
It happens with all older versions too, with and without USE=keybinder. A similar (yet a bit smaller) issue happens with pavucontrol too, so it seems it's something coming from pulseaudio or gtk+ or... With some stracing, I was able to figure out it's constantly receiving messages from /tmp/.X11-unix/X0. This is interrupting the poll() sleep instantly and receiving all those messages is causing huge CPU load. @x11, any idea what that could be and where to look next?
Did some more debugging and it turned out to be problem with xfce gtk3 themes submitting a lot of render requests. Switching to Adwaita reduced CPU load to none.
Sounds like mgorny got to the bottom of the issue, and there's not anything for x11@ to do.
