Description of problem: Use pavucontrol -> pulseaudio uses high cpu usage. Only after Lanuching pavucontrol, pulseaudio uses cpu usage 40%. Version-Release number of selected component (if applicable): 0.9.7-0.1.git20080715.fc10.i386 How reproducible: always Steps to Reproduce: 1. Launch pavucontrol. 2. See pulseaudio on top. 3. Actual results: Expected results: Additional info: pulseaudio-0.9.11-1.fc10.i386.
pavucontrol now shows a volume meter for each device. For that it will configure PA for low-latency mode. Low-latency means high-CPU load. This is hence expected behaviour, somewhat. OTOH it might be a good idea to not configure it for such a low latency though.
Created attachment 319252 [details] ls in pacmd While pavucontrol works, "D: module-alsa-source.c: Wakeup from ALSA! INPUT" prints fast continually. $ pulseaudio -vvv [skip] D: module-alsa-source.c: Wakeup from ALSA! INPUT D: module-alsa-source.c: Wakeup from ALSA! INPUT D: module-alsa-source.c: Wakeup from ALSA!

I am closing this now since as mentioned this is kind of expected behaviour. The "wakeup form ALSA" messages might be a sign of bug 462200.
