Don't know how to configure ffplay to use esound or if it is using esound.

If I use gst-launch with alsa sink decoding time goes down to 23.1 usr 
and 5.2 sys time.

Wow, esound is eating up 8 seconds!!!!
gstreamer still twice as slow as ffplay though :-(

Could it be that ffplay is using mmx optimisations and gstreamer not?
