No AC3 audio in the new release
 

Sorry, didn't read the general discussions. I figured the volume problem would have been posted in here, not 'General'.

Have you tried to register you ac3 filter again ?

Sometimes, it happens to me, and i just have to do this :

regsvr32 c:\windows\system\iviaudio.ax
regsvr32 c:\windows\system\mpgaudio.ax

this two file can also be found in the system32 directory, it depends on your OS.
