Well I sent a private message but I had no answer so I still have no sound at this time.
I tried with the trial of Beyond TV and it works perfectly, that's too bad.
But thanks to Taipan for his help.
Just curious...has anyone heard anything new about this problem with the AVC-3610? I have it when I try and run MediaPortal, but dont have the audio problem when I use MCE in Vista, or BeyondTV.
I build the graph following the filters listed in the xml file. At first, it also only displays picture and no sound. Then I enter in the Crossbar properties from GraphEdit and selected "link related streams"; from this, I'm able to watch video with sound within Graphedit.
