Sorry to resurrect an old thread, but it's the closest I could find after searching LinuxQuestions.org, Google and the Macromedia site/forums for many days.
My Macromedia Flash symptoms are the same as described above: in Mozilla 1.3 the video is fine but audio is choppy, chipmunky (also described as "stuttering" in another forum). All other sound is fine - cds, standalone videos, steaming RealPlayer videos. I have had the same issue with Mozilla 1.2 (I tried Mozilla 1.4 but had too many issues with Java and uninstalled before trying the Flash plugin).
Has anyone in this thread actually found a resolution to this enigmatic issue? I tried messing around with mic settings as described elsewhere and at the Macromedia site, but it did not help.
Really, this isn't a huge issue since I don't go to too many sites that have Flash video/audio, but it's annoying to be met with Alvin and the Chipmunks whenever I do.
My system specs: RedHat 9, Mozilla 1.3, KDE 3.1.3, Toshiba Satellite 1415-S173 notebook, Celeron Mobile 1.80GHz, 512 ram, Intel 82801 CA/CAM AC'97 audio card using i810_audio driver, all upgrades applied via RH liveupdate and apt-get.
Some time ago I installed Mandrake 9.1 and I believe the Flash plugin worked. Since I have RH 9 set up almost 100% to my liking, I don't want to go back just for Flash. I would rather resolve the issue.
TIA for any help anyone might be able to provide!
Peace . . .
