Mp4 with no audio - Sony kdl46ex710

[pacionet]

I am really going crazy trying to play a video from USB on my TV kdl46ex710.

I tried to convert the file in almost every format supported from USB, but I had no luck
(sometimes video with no audio, sometimes audio with no video, somtimes none).

The last attempt: I convert the file in mp4 format, the video is ok, but no audio plays!

VIDEO:
  H264 - MPEG4 AVC PART10
  Resolution: 720x576
  Frames per second: 25

AUDIO:
  MPEG AAC
  Stereo
  44100 HZ

I used AVS Video Converter.

The audio format is wrong ?
