Description Scott Dowdle 2008-07-10 17:43:55 EDT
Problem: Sound will occasionally jitter/stutter for periods of say... 20 seconds or so. While that is happening the mouse pointer will freeze. The mouse pointer unfreezes once the stuck sound becomes normal again. Just to clarify, say the sound is "a". Rather than just "a" I hear "a a a a a a a a a" like it is scratched and repeating itself. It doesn't seem to matter how long the sound plays for... it can be the GNOME startup sound (which is short) or two minutes into a Prince's 1999. There are some times where there is no (obvious) sound output and the mouse pointer will not be visible until after 10 seconds of moving the mouse around. I don't know if the mouse the issue and the sound issue are related to another or not but they appear to be. All other hardware works great including the wired and wireless network adaptors, the display (1440 x 900 widescreen), accellerated video (although I leave Desktop Effects turned off), special keys on the keyboard (screen brightness, volume control, the wireless NIC on/off switch)... I can even plug in an external display and open up the Screen Resolution tool and detect it and use it. Everything works great accept for the periodic stuttering sound and mouse.

If there is any troubleshooting you want me to do, please let me know what and I'll update this report. I hope it is complete enough.

Just to clarify, I have rebooted/cycled power several times since initially noticing this bug and it is immediate upon login and reproduceable every time.
Comment 2 Scott Dowdle 2008-08-12 22:48:13 EDT
I have installed every kernel update since I originally filed this bug report and am currently on kernel-188.8.131.52-108.fc9.x86_64. I am still having the jitter problem. Oddly enough, simply unplugging the laptop from power or plugging it in can cause it to jitter. Any suggestions on how to troubleshoot this problem?
Comment 3 Scott Dowdle 2008-09-12 16:08:10 EDT
I'm closing this bug... as I have discovered it only manifest itself for me in GNOME. I'm a long time KDE user but I was waiting for KDE 4.1 to be released... and it was released / updated in Fedora 9 updates recently... so I installed it and switched to it and the stuttering totally went away. I could actually play multiple audio/video sources and have no issues at all. If I switch back to GNOME, the issue come back. I thought it was a kernel issue but it is somehow related to GNOME or a GNOME library... and I have no idea which or what to even check for. If someone can give me some idea what package to refile this bug under, I'll be happy to do so... but not knowing means I'll just close this one for now.
