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 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.
