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.
We are using ubuntu-desktop, snapshot, found this issue at least w/ 0425 image.
Thanks - eric

i believe i have seen this already when there is permission problem on some /dev/snd... and as such pulse is continuously started/killed/restarted. i don't remember all the details unfortunately, but i think it was because i didn't have the right ACL config in the kernel

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.
Thanks

It might be worth checking the sample rate configured by the card and by pulse. If they mismatch I think Pulse can spend a lot of CPU fixing it up.

Yeah, we tried the default, speex-fixed, and ffmpeg. ffmpeg out performed a bit than the others, but still we found even simply music, pulse eats like 20% CPU.
Paul has more detailed info.

We had this issue with OMAP 4 in the past, when the sound routes and mixing were wrong and incompatible with the board. Once we moved to UCM pulse started to work fine.

Hi Ricardo,
What's UCM?

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.

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)?
For SRU: is there an ubuntu bug for this?

It's bug 644644. It should be in Natty already, and I provided a debdiff for SRU into Maverick more than a month ago, I would like someone to sponsor it some time soon...
644644 is actually two patches, both to help performance, one in PulseAudio and one in GStreamer.
That said, the actual patch for Gstreamer was later reverted upstream for reasons I don't understand / agree with.

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?
