I have for a while been suffering from stuttering playback of certain audio
files. I have now narrowed the problem down to ogg vorbis files and gstreamer.
I don't experince the problem with mp3 or other files and even with vorbis
files it's only noticeable with some specific files. The files that stutter
with gstreamer (I've used banshee and rhythmbox) play without any noticeable
problems with mplayer, so maybe there's something wrong with gstreamer. By
stuttering playback I mean that for a second or less every 20 seconds or so
there's no sound.

I ran the following gst-launch command (adapted from another bug report) and I
cut out a stuttering point from the log: from 0:00:42.594637118 to
0:00:42.893391832. I'll attach that log with a piece from the beginning and the
stuttering point.

For what it's worth, I have an Intel HDA sound chip on an Asus P5Q motherboard.
I use Debian unstable and whatever latest versions of linux and alsa from
there.
