Yes this is an embedded system. As I stated in my previous post aplay, alsamixer and playing MPEG4 movies through gstreamer works just fine. Problem occurs when I try playing ogg files through the pipeline specified.

Can you try to use alsamixer, aplay and arecord to test if your driver is working correctly?
