What do I need to do to get 5.1 on my home theater pc!


Active Member
I have recently built a htpc to view my divx/dvd`s on my plasma.

I have a 5.1 soundcard with an optical spdif output that is connected to the receiver.

However, when I play dvd/dvix that I know is encoded in 5.1 the receiver simply says pcm 44.1 and plays in stereo rather than in 5.1

Any ideas?

What sort of card do you have? It is normal to tell the software player installed to output via the spdif on your soundcard. We need more info!

The soundtrack is most likely encoded with the AC3 codec, so you need to install AC3 filter for it to work (free software).

Yeah sorry was a bit sparse with info lol!

The sound card is a terratec one with an optical out - which is plugged into optical input on receiver.

I have managed to set it up to output via media player in glorious 5.1 but when I use home theater software like meedio it wont output sound. Do I need a plugin?

I am using the ac3 filter software/codec
