Red Hat Bugzilla – Bug 251534
wakes up the sound card when paused
Last modified: 2014-03-16 23:07:57 EDT
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):
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
