GNOME Bugzilla – Bug 441385
Rhythmbox keeps CPU awake even when paused
Last modified: 2007-05-26 10:15:50 UTC
Please describe the problem: I just realised that my CPU doesn't go to power save states C3 and C4 when rhythmbox is running but paused. That means that somehow rhythmbox is keeping the CPU busy enough that it never finds the time to fall asleep. Is it constantly polling something? In my case, the difference ist more than 1.5W, which is almost 10% of the overall power consumption. I can't run Intel's PowerTop to observe it more precisely, because I don't have new enough a kernel. But "luckily" my Thinkpad has this bug that it emits a high pitched noise when the CPU is in C3 and C4, so I can actually hear it. Still, I can also observe the difference when I observe the discharge rate of the battery. Steps to reproduce: 1. Start rhythmbox, play a song, pause it. 2. Observe power usage, for example using /proc/acpi/battery/... 3. Quit rhythmbox 4. Observer power usage again. Actual results: Expected results: Does this happen every time? Other information:
