Can you explain why i can't heard sound with the PCH ?
If it's because of variable bitrate, can you explain how i can simply change it to make the video working ?

Thanks in advance
Alex

Check your Video/Audio setting on the PCH. Make sure that AAC is set to Analog. Retry playing the movie again, report back.

You may want to post some more detailed mediainfo output (especially the screen where audio codecs are mentioned).
Now it looks like there's no audio in it at all.

It's an AAC LC audio track.

Setting the ouput for AAC to Analog under SETTINGS // AUDIO/VIDEO should do the trick.

It is actually an AAC-LC-SBR track which are not supported if I remeber correctly. SBR-oui.

Use MKVmerge to read the file into it and create an MKV. Then use Heartware's audio app to convert to AC3.
