Can't get audio even with the compatible codecs(used Gspot)

Like i said, Gspot recognizes the audio as:
“mpeglayer3 (mp3) (0x0055) ISO/MPEG”
and says i have 2 compatible codecs.
When i play the .avi file i can’t get sound and in Gspot when i render it doesn’t get the Audio Src/Path(but shows render successfully).

Cant get audio even with essetup
