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,

Alex,
Is it possible to merge this before 5/28 release? It's quite critical for 1080P video playback on i.mx53.
