Hello

I am wondering whats the "right" way for a non 5.1 divx to sound on a 5.1 setup.

I have ac3filter installed, and configured for 5.1. However when watching regular dvdrips the sound comes only from the front speakers.

The rear are unused.

So I was wondering, whats the "right" way for this to sound. Should the rear speakers play the stereo sound aswell? Before I reinstalled windows I somehow managed to get it output stereo sound on rear speakers on non 5.1 movies and I think I liked it better. However at the moment I cant figure out how I managed to do that. I think it was somehow using PowerDVD9 sound device. So before I go on changing that, how should it actually sound?


Thanks in advance.

The correct sound would be what you are hearing. The fronts only. Are you sending this audio to a receiver? You'd use one of the receiver's matrix options to simulate surround in your rears and turn it off when you watch a 5.1 source.

I'll add that some receivers will have different options for how to handle your center channel, you might want to play with each and see what you like best.

I don't use the recievers decoding capabilities.


Reciever is set for "external decoder" and just plays what is sent to it over the PL-to-RCA cables. My pc does the decoding, I dont use SPDIF.


Do you guys know of a codec configuration that would allow sound to come out of all channels on non 5.1 movies?

What's the reason you're using analog? To get 24/96Khz from flac?


If not, IMO you'd be better off using the receiver's decoders. This will also allow you to turn on/off the matrix when you need to. You'd have to do the same with the PC. If you setup a matrix 5.1 then you'd have to turn it off when you watch a 5.1 source, otherwise you'd be altering it and screwing it up.

Dunno about PDVD settings, but my PC's Realtek HD Audio Manager Control Panel has a setting in Speaker Configuration (where I have 5.1 set also) called "Speaker Fill":


"Speaker Fill creates a virtual environment for playback of stereo audio sources on surround speaker systems"


Maybe you have something like that on your PC? Or perhaps, you have not yet re-installed your audio chipset's driver which has additional options beyond Windows standard?

No, actually I just assumed that because my reciever is quite old I would get better results going this way and it would be easier to "debug" things that go wrong this way.

As long as your receiver supports the DD and DTS codecs, you won't get better results using analog, and you're actually increasing the complication of your setup.
