GStreamer aplications (Rhythmbox, Banshee) cause high cpu in pulseaudio.
Music Player Daemon and Audacious2 work fine.
How to reproduce it?
gst-launch cdda://1 ! pulsesink
I've got this issue in two ubuntu computers with two diferent versions:
maverick and karmic. The karmic one is a virtual machine.
I file this bug under alsa because I was told to do so but, in my
opinion, it must be a gstreamer o pulseaudio bug. Who knows.
