Sound doesn't works properly on Fedora 11 (and Fedora 10): when moving windows or opening menus, it becomes choppy.
Uh. If you want me to fix your problem I need more information about what's going on. Which type of sound card you have which alsa sound driver is used, which applications you use, and an output of "pulseaudio -vvvvvv" run in a terminal when this happens would be a good start. (You might need to run "pulseaudio -k" first).
I also have same problem in Fedora 10. I have update pulseaudio to the latest version. And update didn't work for me. here's the report of pulseaudio -vvvvvv I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. I: caps.c: Dropping root privileges.

Let's please focus on the F11 case. Please open a terminal. Run "pulseaudio -k". Then run "pulseaudio -vvvv". Then try to reproduce your issue and paste the output that is generated by the aforementiond call while the problem happens into this bug report.
but may be it is possible that same bug is causing all those chopping sound so fixing bug will help both.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Created attachment 347315 [details] Log from pulseaudio while playing an Ogg Vorbis file This log was produced by pulseaudio-0.9.15-11.fc11.ppc on a PowerPC iBook. I ran the following command to play an audio file: gst-launch filesrc location=/path/to/some.ogg ! decodebin ! audioconvert ! pulsesink
these kinds of bugs generally relate to kernel driver problems, and are different for different hardware. I'm closing this one as the initial reporter never provided the requested information. Michael, we would still like to address your issue: if you're still having trouble with the latest Fedora 11 kernel and pulseaudio - please make sure you've tested with these latest updates - please file a new bug, including the pulseaudio output (please re-generate it just in case anything's changed since June) and also the output of 'alsa-info.sh --no-upload'. Thanks! abhijangda, same instructions I have to Michael apply to you, if you can reproduce this in Fedora 11 or 12 (10 is going end-of-life next month, Lennart likely has no time to address problems like this in 10 any more). Again, please file your own bug. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
I concur with comment #7. Unfortunately, I no longer have access to the hardware mentioned in comment #6.
