So basically i formatted my drive installed MCE 2005 on it. Installed windvd6. And now my sound is coming out of only two front speakers. I am using an AV710 with the envy drivers. I installed ac3filter but for some reason MCE is still using the intervideo filter. Now when I change the intervideo audio to 5.1 and save for some reason it still only comes out of 2 speakers, and when I check the setting again it is abck at 2 speakers. Is there any way i can get MCE to use ac3filter. Thats what I had working before with ZP and everything worked. Any ideas?
