5.1 problems

Hi,

Noob registering here to get some much needed support/advice - many thanks in advance.

I have a Windows 7 PC and I am trying to get it to play suitable mkv files in 5.1. I have two pairs of Harman Kardon SoundSticks II. I have one in the green audio port and one in the black port at the back of my pc. I go into playback devices and change my speakers to 5.1 and they all test fine (front left, front right, back left, back right).

I then change VLC settings to 5.1 also.

However, when I play films (with 5.1 audio) I get a strange mix. There is sound coming out of all four speakers, the sounds for the rear speakers seems to be giving me the correct ambient 'rear' sound but I only get very muted sound from the front speakers and no dialogue.

I appreciate something is wrong but I cannot for the life of me figure it out.

Any and all advice is much appreciated.

Dialogue is in the center channel.

Brilliant, thank you. Would never have guessed that. After finding that out I managed to simply change it to 'quadraphonic' and it works brilliantly.
