Steps to reproduce:
1. install alsa-lib 1.0.9
2. install gst-plugins 0.8.9
3. play a ogg or mpc file, for example with gst-launch-0.8 filesrc
location="file.ogg" ! spider ! alsasink

Other information:
this is an example of the output I can see in console:

ghepeu@KazeNoTani ~ $ LC_ALL="C" gst-launch-0.8 filesrc
location="lugradio-s2e12-280305.ogg" ! spider ! alsasink

Execution ended after 15 iterations (sum 1156384000 ns, average 77092266 ns, min

If I downgrade to alsa-lib 1.0.9 rc3 everything works, with both gst-plugins
0.8.8 and gst-plugins 0.8.9. Also, I can still play mp3 files without problems.
I'm using alsa driver 1.0.9, who provides external kernel modules; my sound card
is a Sound Blaster Live! 5.1 EMU10k1, fully supported. I never experimented
audio problems before.
