Description Sean Walberg 2004-12-25 23:21:04 EST

Description of problem:
I upgraded my system from FC1 to FC3 via yum.  When playing sound,
either through XMMS, or even the GNOME system sounds, the output is
choppy, sounding like it is playing at a slower speed with static
thrown in to fill in the gaps.  The same hardware worked fine under FC1.

If I do something like grab a window and move it around the screen,
the sound works normally.

system-config-soundcard detects an Ensoniq 5880 AudioPCI card.  The
test sound exhibits the same behaviour as above.

Gstreamer is set for ALSA as both the source and sink.  I can not run
the test for the sink, though, I get "Failed to construct test
pipeline for 'ALSA - Advanced Linux Sound Architecture'".  However ESD
will test fine, but with the same behaviour.

Comment 1 Sean Walberg 2004-12-26 23:01:08 EST
My comment about moving a window seems a bit ambiguous.  Sound is 
fine while I'm moving the window around, it goes back to choppy once 
I stop.
Comment 2 Dave Jones 2005-07-15 15:22:27 EDT
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

user mailed out-of-band..

"Thanks for the update, but I downgraded to FC1 to fix this problem.  If
I end up upgrading, I'll update the case with my results."

If this reoccurs, please reopen.
