Description of problem: When rhythmbox is paused, the sound card causes ~50 interrupts per second (as measured with powertop). When rhythmbox is *stopped*, there are no interrupts. totem shows a similar amount of interrupts when ran, whether stopped or paused. Ergo, the problem is presumably in gstreamer somewhere. Version-Release number of selected component (if applicable): rhythmbox-0.11.1-1.fc8 totem-2.19.4-2.fc8 gstreamer-0.10.14-2.fc8
Similar behavior is seen in ogg123, and even rec. However, it doesn't happen with 'cat /dev/dsp'. So, most likely culprit is alsa.

note: cat /dev/dsp uses OSS emulation not native alsa
