Description Jason Farrell 2008-11-17 15:06:42 UTC

I know pulseaudio is supposed to be "glitch-free" in F10, but did anyone even *try* logging in to KDE4 even once?

The default startup & shutdown KDE sounds are still as choppy as they were in F9; the startup sound never even finishes skipping before being cut off. This leaves a bad taste in your mouth for KDE, even if subsequent audio playback in other apps is OK.

The Gnome startup sounds on the same F10 system are however glitch-free.

No love for KDE?

It's highly dependent on audio hardware and drivers (kernel).

So, what audio hw are you using?

and,
rpm -q kernel
uname -a kernel

please.

Comment 2 Jason Farrell 2008-11-17 15:35:37 UTC

Using the very common Audigy card:
01:08.0 Multimedia audio controller: Creative Labs SB0400 Audigy2 Value

[root@nano ~]# lspci|grep audio ; rpm -q kernel ; uname -a
01:08.0 Multimedia audio controller: Creative Labs SB0400 Audigy2 Value
kernel-2.6.27.4-68.fc10.x86_64
kernel-2.6.27.5-109.fc10.x86_64
Linux nano 2.6.27.5-109.fc10.x86_64 #1 SMP Thu Nov 13 20:12:05 EST 2008 x86_64 x86_64 x86_64 GNU/Linux

thanks, looks like a dup of bug #466314

*** This bug has been marked as a duplicate of bug 466314 ***

Comment 4 Jason Farrell 2008-11-17 16:10:56 UTC

If it is a dupe (audigy2 buffer underruns) then it's very odd that it's really only KDE syssounds with the bad skipping problem. pulseaudio is otherwise perfectly fine on my system.

Thanks Rex.

btw - why is kde-settings-pulseaudio-4.1-4.20081031svn.fc10.noarch installed if it contains no files or scripts? old dep? ... looks like nothing requires it, but it's still in the kde-desktop comps group.

Comment 5 Rex Dieter 2008-11-17 16:27:24 UTC

kde-settigs-pulseaudio is a metapackage with Requires to pull in all the necessary stuff to make PA work, including:
pulseaudio
pulseaudio-module-x11
alsa-plugins-pulseaudio
xine-lib-pulseaudio

Comment 6 Rex Dieter 2009-02-02 16:29:51 UTC

In the mean time, we've patched xine-lib (1.1.16.1) in an attempt to workaround some of the pa-induced choppiness.
