Bug description:
On the Freescale MX51 platform it has been noticed that Pulse Audio eats up a
signficant amount of CPU that is unacceptable. This is using the now offical
images being produced for the Freescale platform here:
https://wiki.ubuntu.com/BabbageJauntyBetaInstall
I did some findings:
When playing the ogg theora video of big buck bunny. Pulse Audio eats up 15 -
30 % CPU.
http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_stereo.ogg
Pulse audio is eating only 1 - 2% CPU when playing ogg files such as
http://www.vorbis.com/music/The_Abyss-4T.ogg
Also playing mp3s within the software codecs in packages:
gstreamer0.10-ffmpeg
gstreamer0.10-plugins-ugly
When playing through totem pulse audio will then eat up
a bit more averaging 2 - 6 % CPU.
