amarok plays fine with xine engine.

I don';t remember about gstreamer/oss
gstreamer/alsa plays choppy with mp3 files with frequency 32, 24 - not 44,1 
default.

Hardware: Intel 855GM Centrino, AC'97 sound, intel-8x0 kernel module.

Let's compare more details ?

I have a Terratec DMX 6fire 24/96 (ice1712).
I don't think the hardware is at fault though, as aplay and xine seem to have no
problems.

i asked somewhere on our lists - does GStreamer utilize libalsa, which contains 
a database of sound card features? I got no answer :-)

But it is my hypothesis, that sound is choppy, when frequency of sound stream 
does not match some 'natural' freq. of sound card - and GStreamer does not do 
any requantization. It is only a hypothesis.

Did You note some common conditions when sound is choppy and when it is not ?

It's always choppy when played via GStreamer from all apps using it, and it's
not choppy when a test .wav is played via aplay (which uses only alsa libs).
Also, when the GStreamer sound output is switched to OSS in the GNOME GStreamer
settings dialog, a test sound can be played OK. But Rhythmbox and Totem fail to
play via OSS, popping up an error.

It's mine now.

повторяется - sound is choppy in amarok. но и в aplay при выводе через dmix 
тоже.

mplayer играет через dmix нормально.

Судя по тому что написано в их мантисе, баг уже давно исправлен.
