Hi all,
When debugging video playback performance issue, we found that pulseaudio is eating up 100% cpu time. Just in case someone else is having the samilar issue, please let know.
I have had exactly the opposite findings, typically well below 5% usage.
We are using ubuntu-desktop, snapshot, found this issue at least w/ 0425 image.
Can you supply more information on the environment, test case, hardware, etc.
It's on i.MX53 QuickStart board, Cortex-A8, 1GHz, 1GB DDR3. A simple launch of gstreamer to use pulse sink like below:
gst-launch audiotestsrc ! pulsesink
pulseaudio eats 20% CPU.
Paul found the cause and fix to to this issue,

Awesome!
Alex,
Is it possible to merge this before 5/28 release? It's quite critical for 1080P video playback on i.mx53.
We can try to make a SRU for the package and also publish it at the Linaro Overlay, that should cover our images at least.
ack.
SRU probably takes too much time for release, so we should do both, but also verify that it does not have any regression for other (LEB) boards. Kurt, can you try to get this validated on panda (and beagle)?
Rob or Wei can you help validate the fix for this problem? See above defect and 644644 -> https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/644644
For SRU: is there an ubuntu bug for this?
